[UTTARANCHAL-2006]

Detailed Solution for Test: Nervous System - Question 3

The correct sequence of meninges from inner to outer side is:

- Pia mater (innermost)
- Arachnoid (middle layer)
- Dura mater (outermost)

Explanation:
- Pia mater is the innermost layer that closely adheres to the brain and spinal cord.
- Arachnoid is the middle layer that lies between the pia mater and the dura mater.
- Dura mater is the tough outermost layer providing protection and support.

Therefore, the correct sequence is piamater -> arachnoid -> duramater.

Test: Nervous System - Question 4

Somaesthetic or post central area is responsible for :

[UTTARANCHAL-2005]

Detailed Solution for Test: Nervous System - Question 4

The somatosensory cortex is a part of your brain that receives and processes sensory information from the entire body. Other names of somatosensory cortex include somesthetic area and somatic sensory area.This part of the brain is essential for receiving sensory information from the body and processing it to initiate important movements that are required to deal a particular situation. It receives sensations of touch, pain, and vibration from the entire body.

Test: Nervous System - Question 5

Vagus nerve is composed mainly of parasymphathetic fibres. The preganglionic fibres forms a network is known as :

[UTTARANCHAL-2005]

Detailed Solution for Test: Nervous System - Question 5

Auerbach's plexus (or myenteric plexus) provides motor innervation to both layers of the muscular layer, having both parasympathetic and sympathetic input, whereas Meissner's plexus has only parasympathetic fibres and provides secretomotor innervation to the mucosa nearest the lumen of the gut. It arises from cells in the vagal trigone also known as the nucleus ala cinerea, the parasympathetic nucleus of origin for the tenth cranial nerve (vagus nerve), located in the medulla oblongata. The fibres are carried by both the anterior and posterior vagal nerves. The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility.

Test: Nervous System - Question 6

Test: Nervous System - Question 8

Parkinson's disease is associated with :

[JHARKHAND-2002]

Detailed Solution for Test: Nervous System - Question 8

[JHARKHAND-2004]

Test: Nervous System - Question 10

Nissl’s granules are made up of:      [Bihar-2004]

Detailed Solution for Test: Nervous System - Question 10

Nissl's granules are formed by rough endoplasmic reticulum (RER) having rosettes of free ribosomes (polyribosomes) which are a site of protein synthesis.

Test: Nervous System - Question 11

Which part of the brain is affected first in a drunk person :

[Bihar-2004]

Detailed Solution for Test: Nervous System - Question 11

When a person gets addicted to alcohol, many serious health problems can occur due to consumption of alcohol. The first part of brain to be affected first is Cerebellum. The will power and self control of the person gets reduced. Control over emotions and moral sense also gets reduced. Loss of muscle coordination also occurs as cerebellum is affected. As a result, speech becomes incoherent. Inflammation of axons also occur which causes neuritis.

Test: Nervous System - Question 14

The junction between the axon of one neuron and the dendrite of the next is called :

[UP-CPMT 2001]

Test: Nervous System - Question 15

Which one of the followng is a motor nerve ?

[UP-CPMT 2001]

Detailed Solution for Test: Nervous System - Question 15

Abducens nerve is the sixth cranial nerve. It is a motor nerve supplying the lateral rectus muscle of the eye, originating in the dorsal part of the tegmentum of the pons, passing through the cavernous sinus, and entering the orbit through the superior orbital fissure. 
So, the correct answer is option B.
