Question 1

Question: What are ganglia?

Answer 1

Answer: Ganglia are clusters of neuron cell bodies located outside the central nervous system (CNS), usually in the peripheral nervous system (PNS). They are responsible for housing the cell bodies of sensory (afferent) neurons that transmit sensory information to the CNS.

Question 2

Question: What role do afferent dendrites play in sensory perception (e.g., pain and pressure)?

Answer 2

Answer: Afferent dendrites are the sensory receptors at the end of sensory neurons. They detect stimuli (such as pain or pressure) from the environment and send this information toward the central nervous system (CNS). This allows the brain to process the sensation, such as feeling pain, temperature, or pressure.

Question 3

Flashcard 1: Question: What are motor neurons (efferent neurons)?

Answer 3

Answer: Motor neurons carry impulses from the CNS to muscles, glands, and organs, allowing movement or secretion. Their cell bodies are located in the CNS.

Question 4

Flashcard 2: Question: What are interneurons (association neurons)?

Answer 4

Answer: Interneurons connect sensory neurons to motor neurons and process information within the CNS. They are involved in things like reflexes and thought processing. Their cell bodies are located in the CNS.

Question 5

Flashcard 1: Question: What are multipolar neurons and where are they found?

Answer 5

Answer: Multipolar neurons have many processes (dendrites and one axon). They are the most common type of neuron and are found in motor neurons and association neurons (interneurons).

Question 6

Flashcard 2: Question: What are bipolar neurons and where are they found?

Answer 6

Answer: Bipolar neurons have two processes (one axon and one dendrite). They are rare and found in special sensory organs such as the eye and nose.

Question 7

Flashcard 3: Question: What are unipolar neurons and where are they found?

Answer 7

Answer: Unipolar neurons have one process that splits into two branches, with one functioning as an axon and the other as a dendrite. They are found in sensory neurons in PNS ganglia, such as the dorsal root ganglia.
