Nervous System Exam Review

Front

What is a Convergent Circuit?

Back

A type of neural circuit that has many inputs converging to a single output, allowing for the integration of multiple signals.

Front

What is the purpose of the efferent division of the nervous system?

Back

To pass on motor information to effectors, enabling responses to stimuli.

Front

What divisions are included in the Visceral Motor Division?

Back

The sympathetic and parasympathetic divisions, which regulate involuntary bodily functions.

Front

What characterizes a Unipolar neuron?

Back

A neuron with a single fused axon/dendrite, typically found in sensory pathways.

Front

What does Synaptic Plasticity refer to?

Back

Changes in synapses that affect the strength and efficiency of synaptic transmission.

Front

Define Efferent Neurons.

Back

Neurons that carry signals away from the central nervous system to effectors such as muscles and glands.

Front

What is the role of the Sympathetic Division?

Back

To prepare the body for 'fight or flight' responses during stressful situations.

Front

What is the function of the Parasympathetic Division?

Back

To promote 'rest and digest' activities, conserving energy and maintaining homeostasis.

Front

Explain the term Neuromodulation.

Back

The process by which a neuron uses neurotransmitters to control a group of other neurons.

Front

What is a Bipolar neuron?

Back

A type of neuron with two distinct processes (one axon and one dendrite), often found in sensory organs.
