Nervous System Overview

nerves

• 
• Muscles that control movement

• Cells that produce hormones

• Tissues that support organs

Autonomic Nervous System

• 
• A system responsible for voluntary muscle movements

• The part of the brain that regulates emotions

• A network of neurons that only functions during sleep

brainstem

• 
• The outer layer of the brain responsible for higher functions

• A structure involved in memory formation

• The main part of the nervous system that connects to the spinal cord

nerve impulse

• 
• A type of muscle contraction

• A chemical reaction in the brain

• A form of electrical energy

Cerebrum

• 
• A part of the brain that controls balance and coordination

• The brain structure responsible for breathing and heart rate

• The outer layer of the brain that processes sensory information

senses

• Touch, sight, hearing, taste, and smell

• Touch, sight, hearing, taste, and balance

• Touch, sight, hearing, taste, and temperature

• Touch, sight, hearing, taste, and pressure

Peripheral Nervous System

• 
• A network of nerves outside the brain and spinal cord

• The control center of the body

• Responsible for processing sensory information

myelin sheath

• 
• A type of muscle tissue

• A component of the digestive system

• A type of blood cell

Motor Neuron

• 
• A type of neuron that carries signals from muscles to the brain

• A type of neuron that connects sensory organs to the brain

• A type of neuron that is only found in the spinal cord

axon

• 
• A type of neurotransmitter that transmits signals across synapses.

• A protective layer that surrounds the nerve fibers.

• A type of glial cell that supports neurons.
