axes (ăk′sēz′) 1. Anatomically speaking, the ilium is broken down into two parts: the body and the wing. for promoting their purposes. As a person ages, their occipital bones will fuse to the other bones of their skull. The longitudinal axis, or vertically along the thigh, allows for internal and external rotation. It is located next to five of the cranium bones. One of the three planes of the body is known as the transverse plane.Other names for this plane are the axial plane and the cross-sectional plane. Axis, coalition of countries headed by Germany, Italy, and Japan, 1936-45 (see World War II World War II, 1939-45, worldwide conflict involving every major power in the world. In botany, axis is a taper column in the center of some flowers or catkins, about which the other parts are disposed. Its most characteristic feature is the prominent superior projection known as the dens axis, or odontoid process. The overall direction of electrical activity is towards leads I, II and III (the yellow arrow below).As a result, you see a positive deflection in all of these leads, with lead II showing the most positive deflection as it is the most closely aligned to the overall direction of electrical . ( mathematics) A fixed one-dimensional figure, such as a line or arc, with an origin and orientation and such that its points are in one-to-one correspondence with a set of numbers; an axis forms part of the basis of a space or is used to position and locate data in a graph (a coordinate axis) ( anatomy) The second cervical vertebra of the spine axis ( ˈæksɪs) n, pl axes ( ˈæksiːz) 1. (Mathematics) one of two or three reference lines used in coordinate geometry to locate a point in a plane or in space 3. The rotor has exceptional stability at high . The sagittal axis, or forward to backward, allows for abduction and adduction. Body Planes and Sections The directional references allow the body to be divided along three imaginary planes.The frontal plane runs parallel to the long axis of the body produces anterior and posterior sections.The frontal plane is sometimes referred to as the coronal (kor-O-nal) plane, particularly when dealing with sections through the skull.The sagittal (sa-GI-tal) plane also runs parallel . Axis developed Zipstream to address the specific needs of the security . Learn more. In anatomy and medicine (as elsewhere), central is the opposite of "peripheral" which means away from the center. Mathematics. a straight line that bisects at right angles a system of parallel chords of a curve and . There are three axes of rotation. The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. 1983) a central line that bisects a two-dimensional body or figure. axis cylinder neurite (q.v.) The word "peripheral" comes from the Greek "peripheria" ("peri-", around or about + "pherein", to bear, carry). Horizontal (Medio-Lateral) Axis: Runs from side to side Perpendicular to Sagittal Plane Typically flexion/extension 2. The axis' defining feature is its strong odontoid process (bony protrusion) known as the dens, which rises dorsally from the rest of the bone. Axis extends IR-enabled IP camera range. Gross anatomy. or axon (q.v.) of a nerve cell. chickpea pasta prediabetes. axis Anatomy The second bone of the vertebrae (C2), which contains a distinct bony protuberance, the odontoid process (dens), on which the first cervical vertebra (C1, the atlas), which carries the head, rotates. The axis is composed of a vertebral body, heavy pedicles, laminae, and transverse processes, which serve as attachment points for muscles. the second cervical vertebra in reptiles, birds, and mammals, including humans, in which case it is also called the axis. - In human anatomy, the axis is the part of the neck on which the head rotates or the second cervical vertebra. or axon (q.v.) Axis definition: An axis is an imaginary line through the middle of something. The Axis (C2 vertebra) also known as epistropheus forms the pivot upon which the first cervical vertebra (the Atlas ), which carries the head, rotates. The history of this complex system involves discovery of the relevant glands (adrenal, pituitary, hypothalamus), hormones (cortisol, corticotropin, corticotropin-releasing hormone), and the receptors for these hormones.

The moving bone rotates within a ring that is formed from a second bone and adjoining ligament.The pivot joint is exemplified by the joint between the atlas and the axis (first and second cervical vertebrae), directly . 1. Axis An axis is a straight line around which an object rotates. axis: [noun] a straight line about which a body or a geometric figure rotates or may be supposed to rotate. Plant anatomy, or the developmental and compar-ative study of plant cells, tissues, and organs, is a botanical discipline with a long tradition. The human body is also divided into anatomical axes Axis of rotation is an imaginary line (point of rotation) that passes through a joint or the body to describe the movement. Anatomy and Physiology •Anatomy is Structure •Physiology is Function . It forms the pivot upon which the first cervical vertebra (the atlas ), which carries the head, rotates. The AP axis of a region is by definition perpendicular to the DV axis and vice-versa. ( mathematics) A fixed one-dimensional figure, such as a line or arc, with an origin and orientation and such that its points are in one-to-one correspondence with a set of numbers; an axis forms part of the basis of a space or is used to position and locate data in a graph (a coordinate axis) ( anatomy . Body axes are imaginary reference lines, which are used in antomy to describe orientation and location ( topography) of anatomical structures. The main difference between superior and inferior in anatomy is that the term 'superior' describes the anatomical structures located above another whereas the term 'inferior' describes the anatomical structures located below another structure. A straight line about which a body or geometric object rotates or may be conceived to rotate. The second cervical vertebra on which the head turns. Axis Cortex - layer around the central chord or core of the axis, deposited by an axis epithelium. . (Mathematics) a real or imaginary line about which a body, such as an aircraft, can rotate or about which an object, form, composition, or geometrical construction is symmetrical 2. In healthy individuals, you would expect the axis to lie between -30° and +90º.. The radius, also known as the radial bone, is one of the two forearm bones in the human body, with the other one being the ulna.It is instrumental in the shaping and use of hands [1].. Where is the Radius Bone Located in the Arm The axis is the second of seven bones in the cervical spine. ( A from Evans HE, de Lahunta A: Miller's guide to the dissection of the dog, ed 7, St Louis, 2010, WB Saunders.) Many existing side-cutting studies fail to clearly define the orientation of the femoral frame and the knee axis, making comparisons between studies difficult. For example, the head is the most superior structure of the body while feet is the most inferior structure of the body. The transverse plane is an imaginary dividing line that separates the anterior and posterior sections of the body. The human skeleton is made up of 80 bones and is divided into six sections: the skull (22 bones), middle ear ossicles, hyoid bone, rib cage, sternum, and spinal column. the line about which a rotating body, such as the earth, turns. a line about which a three-dimensional body or figure is symmetrical. Static Positional Terms . As part of the hip bone, the ilium, alongside the ischium and pubis, are fused to one another, and, via the sacroiliac ligaments, are attached to the sacrum (the tailbone). ax\i G [axon, axios] › axioma [axis, worthy] pivot axle, axon, axial skeleton B Origin Meaning Example bar G baros weight baroceptors, barometer, hyperbaric, millibar basal L basis a tread (of stairs), stepping, pedestal basal lamina bin L [bin-] bini (< vowel) [two] two together binocular, binate Name: anterior-posterior axis: Synonyms: A-P axis, anteroposterior axis, AP axis, cephalocaudal axis, craniocaudal axis, rostral/caudal, rostrocaudal axis: Definition: An axis that extends through an organism from head end to opposite end of body or tail. The axis is composed of a vertebral body, heavy pedicles, laminae, and transverse processes, which serve as attachment points for muscles. The papillary muscles can be seen in this view. .

(Bayer et al. Anterior components of the axis are composed of: - Axis is also used to describe the two perpendicular lines on a coordinate grid - these are called the X axis and Y axis and meet together at a right angle. a central or principal structure, about which something turns or is arranged: the skeletal axis. The spin axis is defined by the axle of the spinning wheel. The sagittal plane is an anatomical boundary that exists between the left and right sides of the body. The definition of an axis is a real or imaginary line on which something rotates, or a straight line around which things are evenly arranged. (Bayer et al. 3. Skull Bones Protect the Brain and Form an Entrance to the Body. The bones of the appendicular skeleton (the limbs and girdles) "append" to the axial skeleton. Axis Unveils Comprehensive Range of IR Enabled Cameras. Anatomical Directional Terms . See common ventricles examples and types. Transverse Plane Definition. Axis (anatomy) In anatomy, the second cervical vertebra (C2) of the spine is named the axis (from Latin axis, "axle") or epistropheus. Definition: What is the Radius. axon hillock cone-shape region of the neuronal soma from which the axon arises. Quick definitions from WordNet (axis) noun: the center around which something rotates noun: the 2nd cervical vertebra; serves as a pivot for turning the head noun: a straight line through a body or figure that satisfies certain conditions noun: in World War II the alliance of Germany and Italy in 1936 which later included Japan and other nations ("The Axis opposed the Allies in World War II") walnut grove high school homecoming 2021.
