Functional Anatomy Flashcards
Anterior
at the front/ facing forward
Posterior
at the back/ facing backwards
Medial
closer to the body’s midline
Lateral
further from the body’s midline
Deep
on/ nearer the inside
Superficial
on/ nearer the surface
Superior
located at the top/ facing the top
Inferior
located at the bottom/ facing the bottom
Proximal
closer to the torso/ other major point
Distal
further from the torso/ other major point
Unilateral
one side
Bilateral
both sides
Ipsilateral
same side
Contralateral
opposite side
Anatomical Position
facing forwards legs together toes pointing forward arms hang by side face and palms facing forwards
Two types of joint classification
function and movement structure and movement
Function and Movement Classification
synarthroses
amphiarthroses
diarthroses
Synarthroses
immovable joint
united articulation
e.g. sutures
Amphiarthroses
slightly movable joint
surrounded articulation
e.g. intervertebral discs surrounded by 2 vertebrae
Diarthroses
freely movable joint
between articulation
e.g. knee - femur and tibia
Structure and Movement Classification
fibrous joint
cartilaginous joint
synovial joint
Fibrous Joint
dense, connective tissue provide a joint
e.g. sutures, syndesmosis (between radius/ulna, tibia/fibula - connects 2 together)
Cartilaginous Joint
fibro or hyaline cartilage
e.g. synchondroses (epiphyseal growth plate)
Synovial Joint
freely moveable
e.g. knee
Types of Synovial Joint
hinge gliding pivot saddle condyloid/ ellipsoid ball & socket
Hinge Joint
uniaxial
one plane movement
allows flexion and extension
e.g. elbow
Gliding Joint
uniaxial
allows flexion and extension
e.g. intercarpals - 1st row glides over second row
Pivot Joint
uniaxial through spinning action
allows for supination and pronation
e.g. radioulnar joint
Saddle Joint
biaxial
concave on convex
e.g. thumb - carpometacarpal
Condyloid/ Ellipsoid Joint
biaxial
oval convex on oval concave
e.g. radiocarpal joint
Ball and Socket Joint
multiaxial
all plane movement - flexion, extension, adduction, abduction, lateral and medial rotation
e.g. shoulder, glenohumeral joint (hip)
