Question
Explanation / Answer
14. Sensory receptors that monitor the position of joints
BB. Proprioceptors
They are receptors which receive stimuli from within the body especially that responds to position and movement. They provide information on joint angle, muscle length and muscle tension.
15. Plays a central role in basic survival function such as memory
Thalamus
Thalamus as such does not play a vital role in memory, but the limbic system located on both sides of the thalamus is responsible for many higher mental functions like learning and memory. Thalamus is but associated with changes in emotional activity.
17. Sensory receptors that responds to changes in blood pressure
T Baroreceptors
Baroreceptors are located in carotid sinus and aortic arch. They sense pressure changes in the blood by responding to changes in the pressure in arterial wall.
18. Motivation and forethought are localized in the
V Prefrontal lobe
It covers the front part of the frontal lobe. It is concerned with many complex behaviors like planning, motivation etc.
19. Parkinson’s disease is the result of
Z Dopamine deficiency
Dopamine is a neurotransmitter which acts as a chemical messenger between brain cells. It is vital in physical and cognitive functions of the body. Hence, low dopamine levels lead to Parkinson’s disease, a degenerative disorder that affects the motor system.
20. The cranial nerve that has three branches.
Trigeminal nerve
Trigeminal nerve (fifth cranial nerve) is responsible for sensation in face and motor functions like biting and chewing. It is the largest of the cranial nerve consisting of three branches the ophthalmic nerve, the maxillary nerve and the mandibular nerve.
21 The only cranial nerve that are attached to the cerebrum
EE Olfactory nerves
Olfactory nerves are otherwise called first cranial nerves. They have sensory nerve fibers relating to smell.
22 A printed record of the brains electrical activity.
X Electroencephalogram (EEG)
EEG tracks and records wave patterns of brain by attaching electrodes to the scalp with wires. They are used for testing several conditions like seizures, brain tumor, stroke, memory problems etc.
23 Cells that line central and the ventricles of the brain.
Ependyma
Ependyma is involved in the production of cerebrospinal fluid (CSF) and serves as a reservoir of neurogeneration.
24 The relay process for sensory information to the brain higher centers.
U Anterior corticospinal tract
Anterior corticospinal tract is a small bundle of nerve firbes that connect cerebral cortex to the spinal cord. This helps in transmitting sensory information to the higher centers of the brain.
25. The visual cortex center of the cerebrum.
AA. Occipital lobe
The visual cortex center of the cerebrum is located in the occipital lobe in the back of the skull. It plays a vital role in processing visual information.
26 Location of the primary motor cortex.
S Precentral gyrus
Precentral gyrus is an important site of the primary motor cortex. It is involved in planning, control and execution of voluntary movements.
27 The two cerebral hemispheres are separated by
W longitudnal fissure
Longitudnal fissure is a deep groove that separates two cerebral hemispheres.
28 The white matter of the cerebellum
Arbor vitae
White matter is composed of bundles of myelinated axons, which connect various gray matter areas (where nerve cell bodies are located) of the brain to each other, and carry nerve impulses between neurons.
29 The thin partition that separates the first and second ventricles of the cerebral hemispheres.
Y Septum pellucidum
Septum pellucidum is located in the midline of the brain, between the two cerebral hemispheres. It is thin and triangular separating the left and right lateral ventricles of the brain.
30 The cerebellum and pons are derived from the
CC Metencephalon
Metencephalon is the embryonic part of the hind brain that later develops into cerebellum and pons.
