a) Afferent nerves exit the spinal cord, while efferent nerves enter the spinal cord.
b) Afferent nerves transmit motor information, while efferent nerves transmit sensory information.
c) Afferent nerves transmit sensory information to the brain, while efferent nerves transmit motor information from the brain.
d) Afferent nerves only control voluntary movements, while efferent nerves control involuntary movements.

Which of the following best describes the filament theory of muscle contraction?

b) Actin filaments slide over myosin filaments, causing sarcomeres to shorten.
c) Actin and myosin filaments remain stationary while the sarcomere contracts.
d) Sarcomeres lengthen as myosin and actin filaments push each other away.
b) Actin filaments slide over myosin filaments, causing sarcomeres to shorten.
Emma, a 45-year-old librarian, recently experienced a traumatic facial injury during a biking accident. Doctors found that the trigeminal nerve on her right side was severely damaged. Based on Emma’s scenario, is the following statement likely true or false?
“Emma will have problems with chewing due to weakened jaw muscles.”
True
Liam, a 50-year-old chef, complained of persistent dizziness, unsteady gait, and ringing in his left ear after an acoustic neuroma surgery. Doctors confirmed partial damage to the vestibulocochlear nerve.
True/False Statement:
“Liam is likely experiencing balance and hearing problems as a result of vestibulocochlear nerve damage.”
True
The Trigeminal, Facial, and Vagus nerves are crucial for speech production because they control movements of the jaw, lips, and vocal folds, respectively.
True or false?
True
The nerves innervating the diaphragm, the most important muscle to breathing, originate from the three of the thoracic vertebrae.
True or false?
False
