Which one of the following statements is correct?
1 Neurons regulate endocrine activity, but not vice versa
2 Endocrine glands regulate neural activity and nervous system regulates endocrine glands
3 Neither hormones control neural activity nor the neurons control endocrine activity
4 Endocrine glands regulate neural activity but not vice versa
Explanation:
A The endocrine system secretes hormones into blood-stream. These hormones travel to target cells and regulate metabolism, growth, and reproduction the nervous system transmit signals throughout the body. Neurons can indirectly regulate endocrine activity by releasing neurotransmitters that signal to endocrine glands.

Lipofuscin granules are found in:
1 Nerve cell
2 Cardiac muscle
3 Red muscle
4 Cartilage
Explanation:
A Lipofuscin granules are typically found in nerve cells and are commonly known as "age pigment'. They are considered as "wear and tear" product as they accumulate cellular waste or aging cells.

Nissl's granules could be seen in
1 Bone cells
2 Gland cells
3 Myofibrils
4 Neurons
Explanation:
D Nissl's granules are found in neurons. Nissl granules are also called as Nissl bodies or tigroid bodies. They are made up of rough endoplasmic reticulum and ribosomes. They are found in the cell body of neurons and are involved in protein synthesis.

When a neuron is in resting state i.e. not conducting any impulse, the axonal membrane is :
1 Comparatively more permeable of \(\mathrm{K}^{+}\)ions and nearly impermeable to \(\mathrm{Na}^{+}\)ions
2 Comparatively more permeable of \(\mathrm{Na}^{+}\)ions and nearly impermeable to \(\mathrm{K}^{+}\)ions
3 Equally permeable to both \(\mathrm{Na}^{+}\)and \(\mathrm{K}^{+}\)ions
4 Impermeable to both \(\mathrm{Na}^{+}\)and \(\mathrm{K}^{+}\)ions
Explanation:
A The axonal membrane is comparatively more permeable to potassium ions \(\left(\mathrm{K}^{+}\right)\)\& and nearly impermeable to sodium ions \(\left(\mathrm{Na}^{+}\right)\). This is because the concentration of potassium ions is higher inside the neuron than outside, while the concentration of sodium ions is higher outside of neuron than inside. The difference in concentration creates a potential difference across the membrane.
