1. There are five types of muscle tissue found in the body.: False, there are 3
2. cardiac and smooth muscle tissue are both under involuntary control: true
3. the musculocutaneous nerve is part of the central nervous system: false, the
peripheral nerve
4. A motor signal is a signal that is sent from a muscle to the central nervous
system.: false, that is sensory input
5. the cervical plexus contains nerves that innervate the thigh: false
6. tendons connect what type of tissue: muscle to bone
7. Acetylcholine is what type of substance?: neurotransmitter
8. During a muscle contraction which protein myofilament contains
cross-bridges?: myosin
9. What is the thin myofilament?: actin
10. What is the thick myofilament: myosin
11. What must occur for a muscle contraction to stop?: Calcium ions must be
pumped back into the sarcoplasmic reticulum
12. flexor digitorum superficialis action and innervation: flexion of wrist and
digits 2-5, median nerve
13. pronator teres insertion, action, innervation: midlateral surface of radius,
pronation, median nerve
14. vastus medialis origin, action: intertrochanteric line of femur, knee extension
15. peroneus brevis origin, insertion, innervation: lateral, distal fibula, origin =
lateral side of 5th metatarsal, innervation = superficial peroneal nerve
16. your patient sustained an injury to their facial nerve (CN VII). Which actions
would be impaired?: eye closure and raising eyebrows
17. Your patient is having difficulty when asked to bring his chin to his chest.
He is also having difficulty turning his face from side to side. What muscle is
most likely impaired?: sternocleidomastoid
18. A person sustained a back injury to the muscle group closest to the spine.
What muscle group was injured?: Spinalis
19. True or False: When a muscle contracts, the Z lines within a sarcomere
come closer together towards the M line.: true
20. True or False the I bands contain thick filaments: False (I bands contain thin
filaments)
21. What does the H zone contain?: thick filaments only
22. What does the A band contain?: thick and thin filaments
23. Which muscle contracts to enable the main effort required to stand on your
toes?: Gastrocnemius
24. When gluteus maximus contracts, which bone is pulled posteriorly by this
muscle?: femur
1/3
