Nervous system

The Central Nervous System

• Brain and spinal cord
• Stomach and intestines
• Liver and kidneys
• Heart and lungs

What does the Peripheral Nervous System include

• All the nerves that lie outside the brain and spinal cord
• All the nerves that lie inside the brain and spinal cord
• Only the nerves that control voluntary movements
• The bones and muscles of the body

Sensory

• impulse are sent from CNS to effectors (muscle glands) to cause a response

• occurs within CNS; processes incoming sensory input (decision making)

• impulses are sent to the CNS; detect changes inside and outside the body

Integration

• impulse are sent from CNS to effectors (muscle glands) to cause a response

• occurs within CNS; processes incoming sensory input (decision making)

• impulses are sent to the CNS; detect changes inside and outside the body

Motor

• impulses are sent to the CNS; detect changes inside and outside the body

• occurs within CNS, processes incoming sensory input (decision making)

• impulses are sent from CNS to effectors (muscle glands) to cause a response

Which order do impulses travel in

• Dendrites, cell body, axon,

• Cell body, axon, dendrites

• Axon, dendrites, cell body

• Axon, dendrites, cell body,

What is a cell body

• A structure that helps the cell move
• Contains cytoplasm, mitochondria, lysosomes, microtubules, Golgi apparatus, and a nucleus

• A part of the cell that produces energy
• transmits input and carries the input away from the cell body; usually one long fiber

The nervous system_________

• receives information about what is going on in your body as well as what is going on around you.

• tells your body how to react to the information it receives.

• helps your body maintain homeostasis.

• all of the above.

What are the main parts of the neurons to send and receive information (2 parts)?

• nucleus

• axon

• dendrite

• myelin sheath

• Node of Ranvier

what controls your involuntary muscles (digestion, heart, breathing)?

• cerebrum

• cerebellum
• brainstem
