Nerve cells are the primary cells in the nervous system. They are responsible for relaying electrical messages to cells and tissues in other organ systems.

There are 8 pairs of cervical spinal nerves, 12 pairs of thoracic spine nerves, 5 pairs of lumbar spine nerve, 5 sacral nerve pairs and 1 coccygeal nerve that does not come as a pair, this totals up to 31 and Ethylene inhibits cell division, DNA synthesis, and growth in the meristems of roots.

Reflexes are involuntary movements or actions. Some movements are spontaneous, occurring as part of the baby's usual activity and Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. 

Nissel's granules are found in neurons and Cytokinin causes the formation of a larger root system due to an increased elongation of the primary root as well as increased branching.

It is a condition when there is high blood sugar in the body and it caused by when insulin harmone is not secreted by pancreas which maintains blood sugar level in the body.

Pituitary gland is a master gland that produces growth harmones, Cytokinins are a group of hormones that promote cell division in plant roots and shoots and the growth of buds, Insulin harmone is secreted by pancreas which maintains blood sugar level in the body,Thyroxine a hormone that is made by the thyroid gland and is one of the most important thyroid hormones and it also maintains metabolism in the body.

Ductless gland secrete substances known as hormones directly into the bloodstream rather than through ducts. Exocrine glands such as salivary glands discharge their products through ducts, the endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth and metabolism which controls by thyroid gland,  the milk-producing gland of women or other female mammals, Insulin and glucagon are hormones that help regulate the levels of blood glucose, or sugar, in your body.

In the nervous system, a synapse is a structure which serve as Junction between neuron that permits a neuron  to pass an electrical or chemical signal to another neuron; A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals that is why it is largest cell in the human body; Olfactory receptors receptors are responsible for the detection of odorants which give rise to the sense of smell; Thermoreceptors are able to detect heat and cold and are found throughout the skin in order to allow sensory reception throughout the body.

Phototropism refers to the movement of a plant toward a light source; the growth of the parts of plants in response to the force of gravity; the growth or turning of plant roots towards or away from moisture; Chemotropism may be defined as the movement or the growth of the organism in response to a chemical stimulus.

The cerebrum is the largest part of the brain, located superiorly and anteriorly in relation to the brainstem; primary function of Cranial menings is to protect the nervous system. It is three layer protective tissue that surround the neuraxis; olfactory lobe Either member of a pair of lobes in the forebrain, at the anterior end of the cerebrum; the part of the brain at the back of the skull in vertebrates, which coordinates and regulates muscular activity.

The Pancreas is about 6 inches long and sits across the back of the abdomen, behind the stomach. The head of the pancreas is on the right side of the abdomen and is connected to the duodenum (the first section of the small intestine) through a small tube called the pancreatic duct.

The adrenal glands (also known as supra-renal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys.

The thyroid gland is a bilobed organ of the endocrine system located in the front of the neck. It secretes hormones that are involved in human development, growth, and metabolism.

Testosterone is the primary male sex hormone and an anabolic steroid. In male humans, during puberty, the growth of mustache and beard is seen as a sign of growth.

Myxedema refers to a severe form of hypothyroidism than can occur when the condition is left untreated or is not treated sufficiently. The term also applies to the effects that hypothyroidism can have on the skin, making it appear swollen and puffy.

Hitting a ball, speaking and walking are all voluntary actions.
The correct option is D.

When a nerve impulse reaches the muscle, the muscle fibre must move. The simplest notion of movement at the cellular level is that muscle cells will move by changing their shape so that they shorten.
