FLASHCARD QUESTION

Front

What is a reflex arc?

Back

A reflex arc is a neural pathway that controls a reflex action, involving sensory neurons, interneurons, and motor neurons, allowing for quick responses to stimuli without direct involvement of the brain.

2.

FLASHCARD QUESTION

Front

How does the spinal cord function in a reflex action?

Back

The spinal cord processes sensory information and sends signals to the muscles to initiate a response, bypassing the brain for faster reaction.

3.

FLASHCARD QUESTION

Front

What are sensory neurons?

Back

Sensory neurons are nerve cells that transmit sensory information from receptors to the central nervous system (CNS), allowing the body to perceive stimuli.

4.

FLASHCARD QUESTION

Front

What are motor neurons?

Back

Motor neurons are nerve cells that carry signals from the central nervous system to muscles, enabling movement and response.

5.

FLASHCARD QUESTION

Front

What is the role of synaptic vesicles?

Back

Synaptic vesicles are small membrane-bound structures in the presynaptic neuron that store neurotransmitters and release them into the synaptic cleft during neurotransmission.

6.

FLASHCARD QUESTION

Front

What is the synaptic cleft?

Back

The synaptic cleft is the small gap between the presynaptic and postsynaptic neurons where neurotransmitters are released and bind to receptors.

7.

FLASHCARD QUESTION

Front

What are the three layers of the meninges?

Back

The three layers of the meninges, from superficial to deep, are the dura mater, arachnoid mater, and pia mater.
