The Nervous System- LC Biology

This is the name of a nerve cell

• Nervous cell

• Neuron

• Neurotic cell

• Neutral cell

The human nervous system is made up of 2 parts

• The axial and appendicuar nervous systems

• The large and small nervous systems

• The central and peripheral nervous systems

• The central and perpendicular nervous systems

Dendrites carry messages

• Towards the cell body

• Away from the cell body

This insulates the neuron and speeds up the electrical impulse

• Dendrites

• Axons

• Schwann Cells

• Myelin Sheath

This produces the myelin sheath

• Schwann cell

• Dendrite

• Axon

• Neurotransmitter

This is a neuron that carries messages from the sense organ to the CNS

• Motor neuron

• Sensory Neuron

• Interneuron

This carries messages from the CNS to an effector (ie muscles)

• Motor neuron

• Sensory neuron

• Interneuron

This carries messages between nerve cells

• Motor neuron

• Sensory neuron

• Interneuron

This is the minimum stimulation required to send a message along a neuron

• Stimulator nerve

• Threshold

• Minimum requirement law

• All for one law

What chemical carries nerve impulses across a synapse

• NaCl

• Neurotransmitters

• Endorphins

• Hormones
