Question

Multipolar nerve cells are present in
(a) Cochlea
(b) Dorsal root ganglia of spinal cord
(c) Retina of the eye
(d) Brain

Answer 1

It weighs about 3.3 lbs. (1.5 kilograms). It contains around 86 billion nerve cells (neurons) — the "gray matter. It contains billions of nerve strands (axons and dendrites) — the "white matter."These neurons are associated with trillions of associations or neurotransmitters. The largest part of the human brain is that the cerebrum, which is split into two hemispheres. The outermost layer of the cerebrum is the cerebral mantle, which consists of 4 lobes: the frontal, parietal, temporal, and occipital.

Complete answer:
Multipolar neurons are found within the brain and medulla spinalis. they have quite 2 dendrites and an axon. The dorsal root ganglia have pseudounipolar neurons while cochlea and retina have bipolar neurons for instance they have a solitary axon with 2 branches a proximal one and a distal one.

Additional Information: The human mind is that the focal organ of the human systema nervosum, and subsequently the medulla spinalis makes up the focal systema nervosum. The mind comprises the cerebrum, the brainstem, and along these lines the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the knowledge it receives from the sense organs and making decisions on the instructions sent to the rest of the body.
The cerebrum is the biggest aspect of the human mind. It is divided into two cerebral hemispheres. The cerebral mantle is an outer layer of gray matter, covering the core of the substantia alba. The cortex is split into the neocortex and therefore the much smaller allocortex. The neocortex is formed from six neuronal layers, while the allocortex has three or four. Every side of the equator is customarily isolated into four projections – the frontal, temporal, parietal, and occipital flaps.
So the correct answer is ‘Brain’.

Note: The cerebrum is connected by the brainstem to the spinal cord. The brainstem consists of the midbrain, the pons, and therefore the medulla. The cerebellum is associated with the brainstem by sets of plots. Within the cerebrum is that the ventricular system, consisting of 4 interconnected ventricles during which spinal fluid is produced and circulated.
