28
Bifid Process?
Its where the bifid process which is in respect to the spinous process goes from the nucheal ligament and as it nears the spinous processit develops into the superspinous ligament.

D. None of the above
39
Isometric give an example
muscle does not shorten and no movement occurs Ex: Plank
40
Isotonic
muscle shortens and movement does occur Example: Biceps Curl
41
Muscles can only as they “contract” Muscles cannot
Can ONLY pull CAN NOT PUSH
42
What kind of movers have major responsibility for causing a particular movement at a joint What is it called when a muscle acts as an opposer or reverser of a movement? What are muscles called when they help prime movers what is it referred to when stabilization of one bony part at a joint so that all the tension can be used to move the other bony part?
**Prime Movers** - have major responsibility for causing a particular movement at a joint **Antagonists** - oppose or reverse a movement **Synergists** - help prime movers **Fixators** - stabilize one bony part at a joint so that all the tension can be used to move the other bony part
43
Which area does the vertebral artery pass through? A. Transverse Foramen; Thoracic Vertebrae B. Transverse Foramen; Cervical Vertebrae C. Vertebral Foramen; Thoracic Vertebrae D. Vertebral Foramen; Cervical Vertebrae
B. Transverse Foramen; Cervical Vertebrae
