Psychology Paper 2 (Biopsychology - extended)

These are branch-like structures that come out of the nerve cell to connect with other neurons

• Dendrites
• Axons
• Cell body
• Myelin sheath
• Nodes of Ranvier

"Insulates and protects the axon and helps to speed up the electrical transmission"

• Dendrites
• Axons
• Cell body
• Myelin sheath
• Nodes of Ranvier

The gaps in the myelin sheath that force the impulse to ‘jump’ across the gaps along the axon

• Dendrites
• Axons
• Cell body
• Myelin sheath
• Nodes of Ranvier

At the end of the axon these send impulses to the next neuron across the synapse

• Dendrites
• Terminal Button
• Nodes of Ranvier
• Schwann cells
• Nodes of Ranvier

They have long dendrites and short axons.

• Sensory neuron
• Motor neuron
• Relay neuron
• Rachel Neuron

Carry messages from the Peripheral NS to the CNS

• Sensory neuron
• Motor neuron
• Relay neuron
• Rachel Neuron

They have short dendrites and short axons

• Sensory neuron
• Motor neuron
• Relay neuron
• Rachel Neuron

Relay information from the CNS to effectors such as muscles and glands

• Sensory neuron
• Motor neuron
• Relay neuron
• Rachel Neuron

Signals WITHIN neurons are transmitted…

• Chemically
• Electrically
• Through osmosis
• via bluetooth

Signals BETWEEN neurons are transmitted…

• Chemically
• Electrically
• Through osmosis
• via bluetooth
