Exam 1 Flashcards
medial plane
divides the body right and left
sagittal plane
parallel to the median plane, divides the sections into medial and lateral
transverse plane
divides body into cranial and caudal
dorsal plane
divides body into dorsal and ventral
cranial
towards the head
caudal
towards the tail
dorsal
top of the horse
ventral
bottom of the horse
rostral
closer to the nose
proximal
closer to the heart/body
distal
further from the heart/body
anterior
in front of
posterior
behind
axial skeleton
protects the internal organs
appendicular skeleton
supplementary, relating to limbs
long bones
most bones of the limb
short bones
carpal and tarsal bones, sesamoid and patella
flat bones
cranial bones and scapula
irregular bones
pelvis and vertebral column, has large # of projections for tendon attachment
vertebral formula
C7T18L6S5CO15-21
articulate
having joints or jointed segments to form a joint
fibrous joints
immovable, fibrous tissue unites, ossifies with age
suture joints
fibrous, most joints of the skull
syndesmosis
fibrous joints, bones that fuse over time, occur between shafts of long bone
cartilagenous joints
limited movement joints
symphysis
cartilagenous joints, in pelvis and intervertebral discs
growth plates
cartilagenous joint, hyalin cartilage grows and ossifies
synovial joints
movable joints
4 components of the synovial joint
collateral ligament, articular cartilage, fibrous joint capsule and synovial membrane.
diaphysis
shaft of the bone
epiphysis
proximal and distal ends of the bone
epiphyseal line
where the growth plate used to be
periosteum
covers outside of the bone, vessel rich
articular cartilage
covers ends of the bone where it meets another bone in a joint.
nutrient artery
blood for the bone is supplied by the vessels on the periosteum and by the nutrient artery, carrying blood to the endosteum
tendons
connect muscle to bone
ligaments
connect bone to bone
functions of the skeleton
provide a framework for other body tissue to build on, act as a system of levers, protect the inner vital organs, store calcium and phosphorous, produce red and white blood cells
