Overview of Body Flashcards
The Median/median sagittal
vertical plane passing through the midline of the body which divides it into equal right and left halves
(symmetrical left and right)
Sagittal plane
vertical plane that passes parallel to the median
Coronal or frontal
Vertical plane that divides the body into anterior and posterior parts. Perpendicular to the median sagittal plane
Transverse or horizontal
Passes horizontally through the body and divides it into superior and inferior parts
Anterior
In front of another structure
Posterior
Behind another structure
Superior
above another structure
Inferior
below another structure
Deep
further away from the body surface
Superficial
closer to body surface
medial
closer to median sagittal plane
lateral
away from median sagittal plane
proximal
closer to the trunk or origin
distal
away from the trunk or origin
ipsilateral
same side of the body
contralateral
opposite side of body
Anatomical position
Standard position used in anatomy and medicine no matter what position person in. Human body based on person in anatomical position:
1) standing erect- head directed forwards with eyes looking into distance
2) Arms hanging at sides with palm facing forward and thumb laterally
3) Legs placed together with feet together facing forward
Flexion
decreases the angle of the joint. brings two bones closer. typical of hinge joints like knee and elbow
Extension
opposite of flexion. increases angle between two bones
Abduction
movement of limb away from midline
Adduction
opposite of abduction. movement of limb towards the midline
supination
lateral rotation of the forearm causing the palm to face anteriorly (hold the soup)
Pronation
medial rotation of the forearm causing the palm to face posteriorly
Rotation
movement of a bone around its longitudinal axis. common in ball and socket joints
Inversion
movement of the sole towards the midline (turning the sole of the foot inwards or medially up on outside of feet)
Eversion
movement of the sole away from the midline (turning the sole of the food outwards or laterally)
dorsiflexion
lifting the foot so that the superior surface approaches the shin
Planter flexion
depressing the foot (pointing the toes)
Circumduction
a combination of flexion, extension, abduction and adduction. common in ball and socket joints
What are the two regions of the human skeleton?
Axial skeleton and appendicular skeleton
