25 Questions

1.
-outer brain
-part of forebrain

2.

3. neurons communicate across the synapse through these
-chemical messengers that carry nerve impulses across a synapse

4.
the cerebrum is connected by nerve fibers that make up the corpus callosum

5.
branches

6.
transmits visual stimuli from your eye to your brain, allowing you to see

7.
-the space b/t the axon of one neuron and the dendrite of another
-neurons communicate across the synapse using neurotransmitters

8.
-side of brain

9. controls the body's 'fight or flight' response to threat

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

11.

12.
sensory information such as temperature, pain, or pressure is conveyed to the brain along sensory neurons

13.

14.
-front of brain

15.
response commands from the CNS are transmitted back to the musculature along motor neurons

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

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

18. the process of generating an action potential
-can be triggered when a dendrite receives an impulse from a sensory receptor

19. 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

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

21. 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

22.
-largest spinal nerve
-runs from the lower spinal column down the leg

23.
part of brain stem and hindbrain

24.
-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

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