muscular skeletal a&p ch.12 Flashcards
skeletal system tissues
bones: 206
- axial skeletal: central
- appendicular skeletal
cartilage
fibrous connective tissue: ligaments
skeletal system functions
- movement
- supoort
- protection
- calcium storage
- calcium storage
- hemopoiesis
bone structure
- long: growth plates grow length wise
- short- widder wrist
- flat- skull bones
- irregular: vertebrae
- sesamoid- round bones knee cap
periosteum
layer of connective tissue that covers compact bone surface
- serves as the site of muscle attachment (via tendons)
- outer surface contains cells that aid in remodeling and repair (osteoblast)
- richly supplied with blood vessels and nerve fibers
osteoblasts
bone forming
mature into osteocytes
osteoclasts
bone reabsorption
osteocytes
mature permeant bone cells
synovial joints
- most common
- diarthrosis joints
- freely moveable
- many contain ligaments that connect bones to bones and provide support to the joint
amophiarthroses joints
slightly moveable
found in vertebral column
synarthrosis joints
immovable
found in skull and pubic symphsis
synovial joints hinge
elbow joint
synovial joints saddle joint
carpometacarpal joint of thumb
synovial joints ball and socket joint
shoulder joint hip joint
synovial joints pivot joint
dens and acid rotating against atlas
head of radius rotating against ulna
synovial joints condoled joint
altantooccipital koint
