Musculoskeletal System Ch.10 Flashcards
Appendage
any body part attached to a main structure
articulation
Place of union between two or more bones; aka joint
cancellous
latticelike arrangement of bony plates occurring at the ends of long bones
cruciate ligaments
ligaments that cross each other, forming an X within the notch between the femoral condyles
hematopoiesis
Production and development of blood cells, normally in the bone marrow
Skeletal muscles
voluntary or striated muscles i.e. eyeballs, tongue, and bones
Cardiac muscles
makes up most of the wall of the heart. striated
Smooth muscles
involuntary or visceral. found in organs, walls of arteries and respiratory passages.
fleshy attachments
- attaches muscle to bone
- arise directly from bone-weaker than fibrous attachments
fibrous attachments
-connective tissue converges at the end of the muscle to become continuous and indistinguishable from the periosteum.
Aponeurosis
fibrous attachment that spans a large area of bone
tendon
- connective tissue that forms a chord or strap
- attaches muscle to bone
ligament
flexible bands of fibrous tissue that are highly adapted for resisting strains. Hold two bones closely together in a synovial joint.
Flexion
decrease the angle of a joint
extension
increase the angle of a joint
Rotation
moves a bone around its own axis
Inversion
Moves the sole of the foot inward
Eversion
Moves the sole of the foot outward
dorsiflexion
elevates the foot
plantar flexion
lowers the foot (points the toes)
hematopoiesis
producing blood cells with the bone marrow
short bones
- cube shaped
- core of spongy bone aka cancellous bone
- i.e. bones of wrist, ankle, and toes
Irregular bones
Bones that cannot be classified as long or short because of their complex shape.
-i.e. vertebrae, bones of the middle ear
Flat bones
- provide broad surfaces for muscular attachment or protection for internal organs.
- i.e. bones of skull, shoulder blade, sternum
