Which statement about neuroglia is CORRECT?

Answer: C) Set point. For Neuron; Structure and Function, once you lock onto the key mechanism or definition, Set point is the clear fit. If you restate the concept in your own words, Set point is the option that correctly names the structure, process, or principle asked for in Neuron; Structure and Function. So Set point is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other.

Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.

Satellite cells are functionally associated with:

Answer: B) Peripheral ganglia neuron cell bodies. For Neuron; Structure and Function, once you lock onto the key mechanism or definition, Peripheral ganglia neuron cell bodies is the clear fit. If you restate the concept in your own words, the functional job described in the stem is exactly what Peripheral ganglia neuron cell bodies does in Neuron; Structure and Function. So Peripheral ganglia neuron cell bodies is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other.

Ependymal cells are mainly involved in:

Correct option is C, CSF production and circulation. In Neuron; Structure and Function, the accurate description is CSF production and circulation, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what CSF production and circulation does in Neuron; Structure and Function. Then CSF production and circulation is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto CSF production and circulation.

Saltatory conduction occurs due to presence of:

Go with C — Nodes of Ranvier. Within Neuron; Structure and Function, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, cause and effect line up with Nodes of Ranvier — that is the mechanism or reason the stem is pointing to. Holding that picture in mind makes Nodes of Ranvier feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Nodes of Ranvier.

Which PNS glial cell forms myelin around a single axon?

The correct answer is C: Schwann cell. In Neuron; Structure and Function, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, Schwann cell is the option that correctly names the structure, process, or principle asked for in Neuron; Structure and Function. That is why Schwann cell is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Failure of regeneration in CNS neurons is mainly due to absence of:

Correct option is C, Neurolemma. In Neuron; Structure and Function, the accurate description is Neurolemma, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Neurolemma does in Neuron; Structure and Function. Then Neurolemma is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Neurolemma. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Myelination of multiple axons simultaneously in CNS is done by:

The correct answer is C: Oligodendrocytes. In Neuron; Structure and Function, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, Oligodendrocytes is the option that correctly names the structure, process, or principle asked for in Neuron; Structure and Function. That is why Oligodendrocytes is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists.

Which CNS glial cell is primarily involved in immune defense?

Pick B: Microglia. Thinking about Neuron; Structure and Function in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: the functional job described in the stem is exactly what Microglia does in Neuron; Structure and Function. Hence Microglia is correct. Treat this as a building block for the rest of Neuron; Structure and Function; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Microglia.

Neuroglial cells differ from neurons because they:

The correct answer is C: Can divide in adult nervous system. In Neuron; Structure and Function, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, cause and effect line up with Can divide in adult nervous system — that is the mechanism or reason the stem is pointing to. That is why Can divide in adult nervous system is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Gamma motor neurons primarily regulate:

Pick B: Muscle tone and reflex sensitivity. Thinking about Neuron; Structure and Function in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: the functional job described in the stem is exactly what Muscle tone and reflex sensitivity does in Neuron; Structure and Function. Hence Muscle tone and reflex sensitivity is correct. Treat this as a building block for the rest of Neuron; Structure and Function; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.

Motor neurons that innervate extrafusal muscle fibers are called:

Alpha motor neurons (C) is the right choice. This sits at the heart of Neuron; Structure and Function: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: this is mainly a definition check, and Alpha motor neurons is the standard term or meaning used in Neuron; Structure and Function. That reasoning supports Alpha motor neurons. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write Alpha motor neurons from memory, then reveal the letter — that habit builds real recall for Neuron; Structure and Function.

Which interneurons transmit signals over long distances within the CNS?

Go with B — Relay interneurons. Within Neuron; Structure and Function, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Relay interneurons is the option that correctly names the structure, process, or principle asked for in Neuron; Structure and Function. Holding that picture in mind makes Relay interneurons feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Relay interneurons.
