1. Name the 3 types of muscle tissue: skeletal, cardiac, smooth
2. skeletal muscle: have blood & nervous supply to provide movement under conscious control
3. What does it mean that skeletal muscles are under conscious control?: meaning that a person can consciously
decide to use these muscles to complete an action
4. Communication to coordinate movement starts where?: In the brain with a message sent through the spinal cord &
eventually attaches to a muscle 5. What is included in the central nervous system?: brain and spinal cord
6. The CNS (brain and spinal cord) connect to?: peripheral nervous system 7. What do peripheral nerves do:
carry signal from CNS (brain+spinal cord) to muscle to enable movement
8. peripheral nerves: carry signal from CNS (brain+spinal cord) to muscle to enable movement
9. examples of peripheral nerves: spinal nerves (cervical, thoracic, and lumbar), the upper trunk of the brachial plexus,
and the radial nerve.
10. Motor action: (CNS to Muscle) Message from CNS to a muscle is called motor actions
11. Sensory Input (sensation): (Environment to nerves to CNS) Information sent from external environment by nerves to
the central nervous system
12. Central Nervous System (brain & spinal cord) connect to: Peripheral Nervous system
13. Examples of peripheral nerves: 1. spinal nerves (lumbar, thoracic, cervical)
2. Upper trunk of the brachial plexus
3. Radial nerve
14. Peripheral Nervous System (PNS): Carries information into and out of the CNS - carry communication from CNS to muscle
AND carry info from environment to CNS 15. describe the difference between tendons and ligaments: tendons are
connective tissue that attaches muscle to bone at the end.
Ligaments are connective tissue that connect bone to bone. Helping to stabilize joints where bone meets.
16. Tendons: connective tissue that connects muscle to bone
17. Origin vs insertion of a muscle: Origin is a fixed stationary point; insertion is the place that is moved during a muscle
contraction
18. origin: muscles attach to non movable bone
19. insertion: muscles attach to movable bone
20. Muscle action: effect produced by a muscle contraction
- named for action they produce, e.g., flexor or extensor
- i.e. tricep is the primary extensor of the forearm

21. Innervation: a peripheral nerve that supplies muscle with a message from brain 22. describe muscle action and
innervation?: Action of muscle is what effect is produced by the muscle's contraction
The innervation is the peripheral nerve that supplies a muscle with the message from the brain.
23. How many total cranial nerves: 12
24. Where do cranial nerves originate and control?: On the ventral surface of brain
&
controll muscles function of several organs & glands 25. MUSCLES OF FACIAL
EXPRESSION:
26. List all the muscles of the facial expression: (8): BOOM - ZRFT
1. Obicularis Oculi
2. Obicularis Oris
3. Zygomaticus major/minor

5. Frontalis (occipitofrontailis)
6. Buccinator
7. Masseter
8. Temporalis
27. Orbicularis Oculi: close eye; facial nerve CN VII
28. Orbicularis Oris: closes mouth, protrudes lips, presses lips to teeth; facial nerve CN VII
29. Zygomaticus Major: Action: pulls corners of lips upward Innervation: facial nerve CN VII
, Portage Learning: A&P 1 Module 5 - Muscular System
Inferior to zygomaticus minor
(cheek bone)
30. Zygomaticus Major: - Action: pulls corners of lips
upward
- Innervation: facial nerve CN VII
Inferior to zygomaticus minor
(cheek bone)
31. Risorius: - pulls the corners of the mouth posteriorly (grinning)
- cranial nerve CN VII
(attaches to corner of mouth)
32. frontalis (occipitofrontailis): - action: raise eyebrows; wrinkle forehead - Cranial Nerve
VII;
33. Buccinator: - compresses cheek;
- innervation: cranial nerve VII
- location: deep to zygomaticus
34. Masseter: - closes jaw;
- Trigeminal nerve (CN V, manibular branch) (on side of
jaw)
, Portage Learning: A&P 1 Module 5 - Muscular System
35. Temporalis: - Elevates mandible, closes jaw
- Trigeminal nerve (CN V, mandibular branch)
36. Lateral Flexion: aka side flexion, side bending of neck,
moving one of the ears to the shoulder
37. cervical flexion: moving the chin towards the chest
38. cervical extension: moving the chin up
