Human Nervous System

What are the 2 main segments that the nervous system can be divided into?

• the brain and the spinal cord

• central nervous system and the peripheral nervous system

• the nerves and bones

• sensory input and intergration

What are the two divisions of the peripheral nervous system?

• the main control center and spinal cord

• sensory input, and motor output

• somatic and the autonomic

• cerebrum and brain stem

What is the peripheral nervous system?

• any change (inside or outside the body) that brings about a response

• connects body to brain and spinal cord, bundles of nerves throughout the body

• coordinates body activities

• it is responsible for the voluntary or conscious activities

What is motor output?

• the main highway

• the main control center

• the brain sends a response

• the brain and the spinal cord

What are reflexes?

• the main control center

• the brain and the spinal cord

• a message carried by a neuron

• involuntary, automatic response to a stimulus

What does the hypothalamus control?

• any change (inside or outside the body) that brings about a response

• it recognizes hunger, thirst, fatigue, anger and controls body temperature

• blood pressure, heart rate, breathing, and swallowing

• it controls balance and coordination

What does the brain stem control?

• it controls balance and coordination

• the brain and the spinal cord

• it recognizes hunger, thirst, fatigue, anger and controls body temperature

• blood pressure, heart rate, breathing, and swallowing

What does the central nervous system carry?

• bundles of neurons carry impulses from all parts of the body

• voluntary or conscious activities like intelligence and learning

• recognizes hunger, thirst, fatigue, anger and controls body temperature

• all nerves that are not part of the central nervous system

What are the nerves (neurons)?

• The signal carriers

• the main highway

• the brain and the spinal cord

• a message carried by a neuron

What are motor neurons?

• keeps the body in balance

• receives information and sends impulses to the brain

• bright light causes you to squint

• conduct impulses from the brain or spinal cord to muscles
