Anatomy 6.1 - Overview of Nervous system

This is made up of the brain and spinal cord

• Central Nervous System (CNS)

• Peripheral Nervous System (PNS)

• Autonomic nervous system

• Somatic nervous system

All the parts of the nervous system except the brain and spinal cord.

• Central Nervous System (CNS)

• Peripheral nervous system (PNS)

• Autonomic nervous system

• Somatic nervous system

Transmitters that send sensory impulses from the skin, muscles, or joints to the central nervous system

• cell body

• afferent nerves

• neuroglia

• efferent nerves

Transmitters that carry motor impulses from the CNS to the muscles and glands.

• afferent nerve

• neuroglia

• efferent nerve

• synapse

Which of the following are called motor nerves?

• afferent nerves

• efferent nerves

• neurons

• nodes of Ranvier

Which of the following is NOT a subdivision of efferent nerves?

• somatic nervous system

• autonomic nervous system

• nodes of Ranvier

Which of the following is the function of the somatic nervous system?

• controls the cardiac muscles and smooth muscles as well as internal organs

• stimulates skeletal muscles for movement

• makes the connections between the eyes and the brain

• stimulates the ears for better hearing

These are support cells for the neurons in the CNS. while there are 4 types of them, they are commonly called -

• mylean sheaths

• schwann cels

• dendrites

• neuroglia

Area #1 is called the

• axon terminal

• axon

• dendrite

• neurilemma

Area #2 is called the

• axon

• nucleus

• schwann cell

• cell body
