Nervous System

soma

• cell body of a neuron contains the nucleus and other structures common to living cells

• the structures of neurons, which conduct electrical impulses toward the cell body of the nerve cell

• cable where electrical impulses from the neuron travel away to be received by other neurons

• a collection of neuronal bodies found in the voluntary and autonomic branches of the peripheral nervous system

dendrites

• cell body of a neuron contains the nucleus and other structures common to living cells

• the structures of neurons, which conduct electrical impulses toward the cell body of the nerve cell

• cable where electrical impulses from the neuron travel away to be received by other neurons

• a collection of neuronal bodies found in the voluntary and autonomic branches of the peripheral nervous system

axon

• cell body of a neuron contains the nucleus and other structures common to living cells

• the structures of neurons, which conduct electrical impulses toward the cell body of the nerve cell

• cable where electrical impulses from the neuron travel away to be received by other neurons

• a collection of neuronal bodies found in the voluntary and autonomic branches of the peripheral nervous system

ganglion

• cell body of a neuron contains the nucleus and other structures common to living cells

• the structures of neurons, which conduct electrical impulses toward the cell body of the nerve cell

• cable where electrical impulses from the neuron travel away to be received by other neurons

• a collection of neuronal bodies found in the voluntary and autonomic branches of the peripheral nervous system

nerve

• are like cables that carry electrical impulses between your brain and the rest of your body

• make up the most distal portion of the axon within a neuron and contain structures that are critical for neural communication

• an insulating layer that forms around nerves, including those in the brain and spinal cord

• periodic gap in the insulating sheath (myelin) on the axon of certain neurons that serves to facilitate the rapid conduction of nerve impulses

axon terminal

• are like cables that carry electrical impulses between your brain and the rest of your body

• make up the most distal portion of the axon within a neuron and contain structures that are critical for neural communication

• an insulating layer that forms around nerves, including those in the brain and spinal cord

• periodic gap in the insulating sheath (myelin) on the axon of certain neurons that serves to facilitate the rapid conduction of nerve impulses

myelin sheath

• are like cables that carry electrical impulses between your brain and the rest of your body

• make up the most distal portion of the axon within a neuron and contain structures that are critical for neural communication

• an insulating layer that forms around nerves, including those in the brain and spinal cord

• periodic gap in the insulating sheath (myelin) on the axon of certain neurons that serves to facilitate the rapid conduction of nerve impulses

nodes of Ranvier

• are like cables that carry electrical impulses between your brain and the rest of your body

• make up the most distal portion of the axon within a neuron and contain structures that are critical for neural communication

• an insulating layer that forms around nerves, including those in the brain and spinal cord

• periodic gap in the insulating sheath (myelin) on the axon of certain neurons that serves to facilitate the rapid conduction of nerve impulses

sensory neurons

• nerve cells that are activated by sensory input from the environment

• cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these function

• nerve cells that only participate in the local aspects of a circuit

• the electrical potential difference across the plasma membrane when the cell is in a non-excited state

motor neurons

• nerve cells that are activated by sensory input from the environment

• cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these function

• nerve cells that only participate in the local aspects of a circuit

• the electrical potential difference across the plasma membrane when the cell is in a non-excited state
