Q

True or False: Spongy bone is squishy.

A

False: it is porous, but solid.

17
Q

Name 3 types of muscles.

A

Smooth, Cardiac, & Skeletal

18
Q

These connect bone to bone.

A

Ligaments

19
Q

This type of muscle is striated with multiple nuclei per cell. It is attached to bone.

A

Skeletal

20
Q

This is the name of the neurotransmitter released by neurons that begins the process of contraction.

A

Acetylcholine

21
Q

This type of muscle has no striations.

A

Smooth

22
Q

This type of muscle is only found in the heart.

A

Cardiac

23
Q

This is what muscles release in response to acetylcholine.

A

Calcium ions

24
Q

This type of muscle is found in organs like the stomach, eyes, blood vessels, and digestive tract.

A

Smooth

25
Q

The humerus, femur and pelvis all belong to this skeleton.

A

Appendicular

26
Q

During contraction, cross-bridges do this.

A

Bend, pulling actin & myosin together.

27
Q

The type of joint found in your shoulder & hip.

A

Ball & Socket

28
Q

During relaxation, neurons release this.

A

Acetylcholinesterase

29
Q

Name 4 steps of muscle contraction.

A
  1. Brain sends motor impulse
  2. Neuron releases acetylcholine.
  3. Muscles release Ca++ ions.
  4. Cross-bridges bend, pulling actin & myosin together.q
30
Q

Name 4 steps of muscle relaxation.

A
  1. Brain releases motor impulse.
  2. Neuron releases acetylcholinesterase.
  3. Ca++ ions are reabsorbed.
  4. Cross-bridges straighten, and actin & myosin slide AWAY from each other.
