FINAL JEOPARDY

What are the 2 structures that create the Central Nervous System?

• Peripheral Nervous System and the Central Nervous System

What is the function of the Nervous System?

• The Nervous System collects information about the body’s internal and external environment, processes that information, and responds to it.

What part of the brain is associated with emotion, behavior and memory?

• The Limbic System

What are the 3 major parts of the brain, responsible for processing and relaying information?

• Cerebrum, Cerebellum, and Brain Stem

________ experiences change many of the patterns of neuron connections in the brain. These new cells originate in regions associated with learning and

memory

• Sensory

This body system takes in oxygen, as well as exhausts CO2 from the body

• Respiratory

This body system incorporates the largest organ in the body. It also protects against infection

• Integumentary System

The kidneys, bladder and ureters are apart of this body system

• Excretory System

Supports the body and protects internal organs

• Skeletal System

This body system controls growth, development and metabolism. Regulates hormones

• Endocrine System

These receptors of the PNS creates movement of the muscles in response to a stimulus

• Motor receptors

Stimulus Sensory Receptors ___________ CNS

• Sensory Neurons

This sensory receptor is found in the eyes and responds to light

• Photoreceptors

The ______________ regulates activities that are involuntary, or not under conscious control

• Autonomic Nervous System

Thermoreceptors are found in these 2 areas of the body

• Skin and hypothalamus

How many Cranial Nerves are there?

• 12

What is the purpose in testing Cranial Nerves?

• To determine the area of the brain that has experienced trauma. By knowing this, it makes treatment easier to determine.

Cranial Nerve VII, is tested by smiling, frowning and puffing out cheeks

• Facial

Cranial Nerves go through openings in the skill and stimulate regions of the _______ and _______.

• Head and neck

This nerve is responsible for lateral eye movement. Cranial Nerve VI

• Abducens

This part of the neuron is the first receives the stimulus. Functions almost like “branches of a tree”

• Dendrites

This structure of the neuron functions like “the brain” of the cell

• Nucleus

Also known as the Soma

• Cell Body

Acts as the insulator to the axon

• Myelin Sheath

This structure of the neuron is the very end of the neuron. It is where the axon breaks into different branches

• Axon terminal

What is the disease commonly associated with football players and soldiers, caused by continuous head trauma and leads to

significant depression?

• Chronic Traumatic Encephalopathy
