Neural Homeostasis Definitions

Select the best definition for effector

• Something that causes an effect

• A muscle or gland that responds to a stimuli

• A part of the body that receives messages from stimuli

• A part of the nervous system

Select the best definition of axon

• a substance that inhibits the growth of bacteria

• The end of a nerve cell

• The part of a nerve cell that conducts an action potential away from the cell body towards the next nerve cell

• The body of the cell containing the nuclues

soma

• The part of the axon that contains the nucleus

• The axon

• The part of the neuron that carries the nerve impulse

Select the best definition of dendrites.

• A long extension of cell body that increases surface area for receiving inputs from neurons or sensory receptors

• Receive nerve responses

• The edge of the soma

What is a neuron and what is it comprised of

• a nerve cell that sends messages through the nervous system

• A sensory or motor neuron

• A nerve cell that includes a soma, dendrites and cell body

Schwaan cell

• Mylein sheath

• A fancy name

• Cells that protect the axon and allow nerve impulses to travel faster

• type of cells of the peripheral nervous system that help form the myelin sheath around the nerve fibers

Sensory Neurons

• Contain the cell body within the axon

• Have the cell body at the terminal of the cell

Define synaptic transmission

• The process by which one neuron communicates with another. It must cross over the synaptic gap between the presynaptic neuron and post-synaptic neuron

• The movement of a nerve impulse between nerve cells along the axon and between soma bodies

• The movement of a nerve impulse

• Synapses

Motor Neurons

• Transmit information from the CNS to the tissues and organs

• Carries impulses from the brain to the spinal chord

• Carry messages from finger tips to the CNS

Sensory Neurons

• Transmit messages from sensory receptors to the CNS

• Transmit information from the CNS to the tissues and organs

• Send messages

• Transmit nerve impulses
