HUMAN A&P 1: MODULE 5 PROBLEM SET Questions with Correct
Solutions
Question:
1. Cardiac, Skeletal, and Smooth
Answer:
Name the three types of muscle tissue found in the body
Question:
2. Skeletal muscles are under conscious control, meaning that a person can consciously
decide to use these muscles to complete an action.
Answer:
What does it mean that skeletal muscles are under conscious control?
Question:
3. What structures are included in the central nervous system?
Answer:
Brain and spinal cord
Question:
4. Messages from the central nervous system to a muscle are called motor actions. Nerves
also carry information from the external environment and the muscles to the central nervous
system, called sensation or sensory input.
Answer:
Describe a motor action vs. sensory input in terms of the nervous system
Question:
5. False
Answer:
True or false: The brachial plexus supplies nerves to the lower extremities.
Question:
6. Tendons are connective tissues that connect skeletal muscle to bone at each end.
Ligaments are connective tissue that connects bone to bone, helping to stabilize joints where
bones meet.
Answer:
Describe the difference between tendons and ligaments
,Question:
7. The origin is the bony site of attachment that is stationary during the movement. The
insertion of a muscle is the bony site of attachment that is moved by the muscle contraction.
Answer:
Describe the meaning of muscle origin and insertion
Question:
8. The action of the 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.
Answer:
Describe the meaning of muscle action and innervation

Question:
18. Muscles of facial expression
Answer:
AI-GENERATED STUDY RESPONSE (VERIFY): Facial expression muscles include orbicularis
oculi, orbicularis oris, buccinator, zygomaticus major and minor, frontalis and platysma; most
are supplied by cranial nerve VII.
Question:
19. Sternocleidomastoid Origin: sternal end of clavicle and manubrium Insertion: mastoid
region of skull Action: Bilateral: neck flexion Unilateral: turns face to opposite side
Innervation: accessory nerve (CN XI)
Answer:
Identify the muscle indicated below. Also name its origin, insertion, action, and innervation.
Question:
20. Semispinalis Capitis Origin: articular processes of inferior cervical & transverse process
of superior thoracic vertebrae Insertion: occipital bone Action: -Bilateral extend head
-Unilateral laterally flexes neck to same side Innervation: spinal nerves
