C2.2 Neural Signalling

The synapse or junction of the axon terminal of a motor neuron with the motor end plate, responsible for muscle contraction.

• Neuromuscular Junction

• Synaptic Cleft

• Axon Terminal

• Motor Neuron

R²

A measure used in statistical analysis that assesses how well a model explains and predicts future outcomes.

• Coefficient of Determination

• Correlation Coefficient

• Standard Deviation

• Mean Absolute Error

Cells in the peripheral nervous system that produce the myelin sheath around neuronal axons.

• Oligodendrocytes

• Astrocytes

• Schwann Cells

• Microglia

A fatty substance that surrounds the axon of some nerve cells, forming an electrically insulating layer.

• Myelin

• Cholesterol

• Phospholipid

• Sphingomyelin

Relating to or denoting nerve cells in which adrenaline (epinephrine) or noradrenaline (norepinephrine) acts as a neurotransmitter.

• Adrenergic

• Cholinergic

• Serotonergic

• Dopaminergic

The network of nerve cells and fibers that transmits nerve impulses between parts of the body.

• Nervous System

• Circulatory System

• Endocrine System

• Digestive System

A short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls.

• Action Potentials

• Resting Membrane Potential

• Graded Potentials

• Repolarization

A postsynaptic potential that makes the neuron more likely to fire an action potential.

• EPSP (Excitatory Postsynaptic Potential)

• IPSP (Inhibitory Postsynaptic Potential)

• Action Potential

• Resting Membrane Potential

Sensory receptors that respond to potentially damaging stimuli by sending signals to the spinal cord and brain.

• Thermoreceptors

• Nociceptors

• Photoreceptors

• Mechanoreceptors

Glial cells in the central nervous system that produce myelin.

• Astrocytes

• Microglia

• Oligodendrocytes

• Ependymal cells
