Explanation

$\textbf{Correct option: (C)}$

$\textbf{Solution:}$

$\textbf{Option (C):}$

$\bullet$ (A-x) Nissl's granules -------------- Ribosomes.

$\bullet$ The nissl's granules found in the cell body of the neuron are ribosomes that synthesis proteins.

$\bullet$ (B-vi) Tract ---------------- Collection of nerve fibres.

$\bullet$ Tract is referred to as collection of nerve fibres having common origin and destination such as optic tract that arise from the blind spot of the retina is collection of nerve fibres that carry the signal to the brain via auditory nerve.

$\bullet$ (C-ii) Muscle tone --------------- Cerebellum.

$\bullet$ The cerebellum is the smallest region of the brain that functions in controlling motor activities. It is concerned with balance, equilibrium, and muscle tone.

$\bullet$ (D-i) Star- shaped glial cells --------------------Astrocytes.

$\bullet$ Astrocytes are the star-shaped glial cells of the central nervous system.

$\bullet$ (E-iv) Outermost brain envelop --------------- Dura mater.

$\bullet$ The brain and spinal cord is covered with three meninges dura mater, arachnoid and pia mater. The outermost layer that envelops the arachnoid mater of the brain is called the dura mater.

Hence, the correct option is (C)

Synaptic vesicles are found in ______

0%
Presynaptic neuron
0%
Post synaptic neuron
0%
Synaptic cleft
0%
None of the above

Explanation

$\large\textbf{Correct Option: A}$

$\textbf{Solution}$

Option A)

$\textbf{Presynaptic neuron}$

$\bullet$ Synaptic vesicles (SVs) are small, electron-lucent vesicles that are clustered at presynaptic terminals which store neurotransmitters and release them by calcium-triggered exocytosis.

$\bullet$ Vesicles play an important role in propagating nerve impulses between neurons.

$\bullet$ The area in the axon that holds groups of vesicles is said to be the axon terminal.

Option B)

$\textbf{Postsynaptic neuron}$

$\bullet$ Postsynaptic neuron has the receptors which receive the neurotransmitter.

Option C)

$\textbf{Synaptic cleft}$

$\bullet$ Synaptic cleft is the empty area present between the two neurons.

Hence the correct answer is A)

$\textbf{Presynaptic neuron}$
