Anatomy Coordinate System Flashcards
Views and aspects
anterior vs posterior, superior vs inferior
Anterior
The front of the body
Posterior
The back of the body
Superior
Closer towards the head of the body
Inferior
Further from the head of the body
Anatomical position
Standard anatomical position of the body is an erect posture with face forward, arms at sides, palms forward, finger and thumbs in extension
Anatomical position is used fro
reference for all coordinate systems and planes
Posture
Position of the entire body or a segment relative to gravity
Static (anatomic) posture
The position of the entire body relative to the position of one segment to another
Dynamic (physiological) posture
Intended to have neuromuscular activity to maintain the CG relative to the base of support
Extension/flexion
Bending of the body in the anterior/posterior plane due to CG
Lateral (left/right) bending
Bending of the body to the left or right of CG
Transverse (left/right) rotation
Rotation of the body left/right of standard anatomical position CG
Supine
Laying down face up (opposite of prone)
Prone
Laying down face down (opposite of supine)
Proximal
Closer to the center of the body or the point of attachment (opposite - distal)
Distal
Away from the center of the body of the point of attachment (opposite - proximal)
Coordinate system
Cartesian coordinate system is used (z points up and down, y is left to right, x is anterior to posterior)
Coordinate system - three defined planes
Sagittal, coronal (frontal), transverse
Sagittal plane
Splits left side of body and right side of body in standard anatomical position
Coronal plane
Splits anterior and posterior side of body in standard anatomical position
Transverse plane
Splits Top and bottom half of body in standard anatomical position
Pelvic ring bones
Ilium, sacrum, pubic symphysis
Pelvic ring defines a
stable coordinate plane origin for use in gait
Basic anatomy
Adult has 206 bones, babies have more but they fuse together
Foot anatomy - bones
Talus, navicular, cuneiform, metatarsal, phalange, cuboid, calcaneus
Skull anatomy - some important bones
Zygomatic, mandible, temporal, occipital, parietal
Thorax
Ribcage - Increases stiffness of the torso; plays an important role in the kinematics of the torso; consists of the scapula, 12 vertebrae, 12 pairs of ribs, sternum
