Anatomy Flashcards
What is the connective tissue on the end of bones?
cartilage
What connects muscle to bone?
tendons
What is the issue with an overstretched ligament in relation to joints?
It can’t hold bones to bones very well, creating unstable joints.
Can torn ligaments be healed by the body?
No; surgery is needed to reattach the ligament.
Do ligaments have elasticity?
no; very little
Do tendons or ligaments turn into muscle tissue?
tendons
Can tendons stretch?
yes
Do muscle cells contract?
Yes; muscles have contractile cells that contract with motor nerve stimulation.
Do fasica cells contract?
No; fascia does not have contractile cells.
What time does muscle stretching hit its maximum?
In two minutes of sustained stretching.
What percentage of max stretch is hit after 1 minute of muscle stretching?
92%
Is it possible to engage the fascia in isolation?
no
What is Wolff’s Law?
Bones recognize use and adapt to support that use. Bone grows and remodels based on the stress/demands placed on them.
What are synarthrodial joints?
bones that are fused together; ie. in the skull
What are amphiathrodial joints?
bones held together by dense ligaments; ie. SI joint in the pelvis
What are diathrodial joints also called?
synovial joints
What are synovial joints?
freely moveable joints with capsule that contains synovial fluid
What does synovial fluid do?
lubricates the joint and keeps the cartilage healthy for easier & smoother movements
Where does limited ROM come from in synovial joints?
tight muscles or ligaments
What type of synovial joint are the hips?
ball and socket joint
What type of synovial joint are the elbows?
hinge joint
What type of synovial joint are the wrists and ankles?
plane joint
Which joint wobbles from side to side?
hinge joint
What is ROM?
range of motion; refers to how far a joint can move
