Nervous System Review

Brain anatomy

100

What is the largest part of the brain? Name all four parts.

Cerebrum; frontal, occipital, temporal, parietal

200

Describe the difference between the Wernicke's and Broca's area.

Broca's - ability to speak, conscious of speech

Wernicke's - lack of language comprehension

300

Which gland is described as the "master gland" and why is it called that?

Pituitary; releases hormones that regulates other glands 

400

Name all four core parts of the brain.

Cerebral hemispheres (cerebrum)

Diencephalon

Brain stem

Cerebellum

500

Studies have found that individuals that contain structural abnormalities in this part of the brain struggle with identifying danger and feeling fear. What part of the brain is this?

The amygdala.

Nervous system organization

100

Name the two parts of the nervous system.

Central nervous system and peripheral nervous system.

200

Support cells are responsible for:

Supporting, protecting, and insulation neurons.

300

Describe the three steps involved in stimulus interpretation.

Sensory input - gather input

Integration - process and interpret stimulus

Motor output - respond to stimulus

400

The autonomic nervous system is responsible for:

Involuntary control of smooth & cardiac muscle and glands.

500

Describe the location and function of the Central Nervous System.

Dorsal body cavity - integrating and command centers; interpret sensory information & give out instructions

Neurons

100

What is the name of a nerve cell?

Neuron.

200

Describe the function of neurons.

Transmit nerve impulses from one part of the body to the other

300

The nucleus within a neuron contains:

The cell's DNA

400

Compare and contrast dendrites and axons.

Dendrites—conduct impulses toward the cell body

Axons—conduct impulses away from the cell body

500

In individuals who have multiple sclerosis their immune system begins to attack their myelin sheaths. What are the expected consequences of this? What symptoms can you expect?

Decrease in rate of nerve impulse transmission. Loss of muscle control, visual and speech impairment.

Random

100

The medulla is responsible for:

Regulates many bodily activities, including heart rhythm, breathing, blood flow, and oxygen and carbon dioxide levels.

200

What cells make up the majority of the nervous system?

Neurons.

300

Name three functions of the frontal lobe.

Emotions, language comprehension, complex problem solving, decision making, planning and organizing, etc.

400

All team members must individually name and show the physical location of two bones. No bone may be repeated, specific name must be used (e.g., cannot say thigh bone).

Femur, mandible, ribs, phalanges, patella, clavicle, etc.

DAILY DOUBLE (1,000 pts)

Describe how sedatives create numbness.

Sedatives block sodium entry during a nerve impulse which prevents the impulse from occurring. This prevents that part of the body to send out messages.
