25 Questions

1.
sends and receives signals from skeletal muscle, which is under conscious control

2. Which of the following lists the subdivisions of muscle tissue in order from smallest to largest?

3. neurotransmitter that triggers the contraction of skeletal muscle
-released at the synapse b/t a motor neuron and muscle fiber
-triggers the release of Ca2+, which causes actin and myosin to interact

4.
-largest part of the brain
-covering of entire brain
-responsible for thought and perception, as well as visual and auditory processing
-divided into 2 halves, connected by nerve fibers that form the corpus callosum, which are further subdivided into 4 lobes: frontal, parietal, occipital, and temporal

5. most axons are insulated w/ this
-helps to increase the speed of the electrical impulse along the nerve cell

6. messages are communicated b/t the brain and muscular system by way of these electrical signals, which travel along the axon
-occur at an 'all or none' fashion; either one is triggered or isn't

7. prevent impulses from being transmitted effectively and can result in uncoordinated muscle movement
-ex: multiple sclerosis

8.

9.
-back of brain

10. Clients who are bedridden for prolonged periods are at risk of muscular atrophy. Which of the following explains the primary cause of muscular atrophy?

11. peripheral nerve damage
-can lead to muscle weakness, tingling sensations, numbness, or paralysis depending on the degree and location of the injury

12.

13.
-consists of the neurons (nerve cells) that send and receive signals throughout the body
-all nerves that exist outside the CNS
-can be further divided into the somatic nervous system and autonomic nervous system

14.
-middle/top of brain

15. single motor neuron can communicate to numerous muscle fibers at once
-group of muscle fibers enervated by a single motor neuron

16.
-outer brain
-part of forebrain

17.
sensory information such as temperature, pain, or pressure is conveyed to the brain along sensory neurons

18. contain both sensory fibers and motor fibers
-transmit both sensory and motor signals from the spinal cord to a specific area of the body

19. 12 sets of cranial nerves
-reach the interior of the brain
-each have a specific function

20.

21. Movement of the eye is coordinated by?

22. allows the body to sense and respond to environmental changes, both those that arise internally as well as those caused by external stimuli
-consists of 2 parts: central nervous system and peripheral nervous system

23.
chain

24.
the cerebrum is connected by nerve fibers that make up the corpus callosum

25.
-muscle control and balance are controlled by cerebellum
-dense cluster of neurons located at the base of the brain
