Question

Neurosecretory cells occur in
A) Hypothalamus
B) Cerebral cortex
C) Medulla oblongata
D) Corpus callosum

Answer 1

Hint:Neurosecretory cells are the type of nerve cells which convert the neural signals to chemical signals. They produce neuropeptides which are released directly to the bloodstream. This neuropeptide controls the physiology.

Complete answer:
To answer this question, we must know about the neurosecretory cells and its function.
>The neurosecretory cells are present in the multicellular animals. They have unusually large nucleus, axon endings. They are found in the medial and lateral part of the brain called the hypothalamus. They release neurohormone which travels along the neuronal axons and are released into the bloodstream. The neurohormones include vasopressin and oxytocin.
>Cerebral cortex contains nerve endings of neurons as well as it is rich in blood vessels. It controls the voluntary activities of our body.
>Medulla oblongata forms the brain stem. It controls all the involuntary activities of our body.
>Corpus callosum is an important structural and functional part of the brain. It connects the two hemispheres of the brain.

Additional Information: Hypothalamus connects the endocrine system with the nervous system. It is directly pituitary to tart or top making hormones. It is involved in daily activities like eating, drinking, controlling body temperature, maintaining energy, stress control etc.

Thus the correct answer is (A). Neurosecretory cells occur in Hypothalamus.

Note:Conn’ syndrome can be treated by removing the tumour by the procedure called adrenalectomy. It helps in lowering the potassium level in the blood which results in normalisation of blood pressure. This syndrome is generally treatable. If untreated, this disease can lead to heart attack, stroke, heart failure, kidney failure.
