cranium
spinal canal
CNS
ventral cavity
thorax
abdomen
contains viscera
inflammation of the thorax
pleuritis
inflammation of abdomen
peritonitis
knee
common name to carpus
hock
common name to tarsus
functions of bones
support
protection
leverage
storage
blood cell formation (hematopoiesis)
bone
- second hardest natural substance in the body
- composed of cells embedded in a matrix
ossification
hardening of the matrix
osteoblasts
cells that form bone
osteocytes
osteoblasts surrounded by bone
osteoclasts
remodel and remove bone
spicules (cancellous)
bone marrow in spaces
light
arranged
compact bone
outside layer of all bones
shafts of long bones
Haversian systems (concentric layers of ossified bone matrix around central canal)
red bone marrow
hematopoetic tissue
younger animals
yellow bone marrow
adipose connective tissue
adult animals
can revert to red bone marrow
fibrous joint
immovable; sutures in skull
cartilaginous joint
slightly movable; mandibular symphysis
synovial joint
freely movable; hip socket
arthro-
joints

cartilage
costo-
ribs
osteo-
bone
types of synovial joints
hinge
gliding
pivot
ball and socket
hinge joints
only flexion and extension
gliding joints
rocking motion of one bone on another; carpus
pivot joints
one bone rotates on another; atlas and axis
axial skeleton
head and trunk (central part of body)
appendicular skeleton
bones of the limbs
visceral skeleton
bones formed in soft organs
basic tissues of the body
muscle
epithelial
connective
nervous
muscle tissues
provide motion
maintain posture
generate heat
epimysium
well-defined group of cells surrounded by fibrous connective sheath (skeletal)
action of muscles
adductor
abductor
shape of muscles
deltoid
trapezius
location of muscles
triceps brachii
direction of muscle fibers
transversus abdominus
number of heads or divisions
quadriceps femoris
attachment sites
sternocephalicus
functions of head and neck skeletal muscles
facial expressions
mastication
sensory structures
support and move head, neck, and front legs
function of limb skeletal muscles
locomotion and movement
neuromuscular junction
site where ends of motor nerve fibers connect to muscle fibers
motor unit
one nerve fiber and all the muscle fibers it innervates
function of pelvic limb skeletal muscles
locomotion
functions of abdominal skeletal muscles
- support abdominal organs
- help flex the back
- participate in defecation, urination, and parturition
respiration
functions of skeletal muscles of respiration
increase and decrease size of thoracic cavity
- inspiratory muscles increase and expiratory muscles decrease size
