MOTOR NERVES

Certain nerve fibers receive impulses or stimuli which are imparted to the muscles causing them to act. Such nerves are called Motor nerves. These impulses originate in the nerve center and travel outward, along the pathway of the blood vessels to the muscular tissue and are also known as EFFERENT NERVES. Where the impulse produces a secretion the Motor nerve is then referred to as SECRETORY. Motor Nerves originate in the ventral column of the spinal cord.

SENSORY NERVES

These are the nerves that control the senses: sight, smell, hearing, taste, and feeling. They differ from motor nerves because they end in the outside surfaces of the body and carry impulses inward to the nerve center. These nerves are known as AFFERENT or RECEPTOR Nerves. They are found in the dorsal column of the spinal cord.

MIXED NERVES

Nerves which contain cells capable of receiving impulses from the nerve center and causing muscular action as well as cells which send messages to the nerve center recording sensation are called mixed (Motor and Sensory) nerves.

PERIPHERAL NERVES

Those located on the external surfaces are known as peripheral nerves.

NEURONS

A neuron is a complete nerve cell, made up of cell body and its extensions or processes called DENDRONS and AXONS. The nervous system consists of an enormous number of Neurons which are covered by protective membranes of connective tissue, provided with blood vessels and lymph channels for the purpose of nutrition and respiration.

NEUROSIS

A disease which prevents the nervous system from properly performing its normal function is called NEUROSIS. A person having a disordered nervous system is referred to as a NEUROTIC. Neurosis is caused by a number of things, but in this age of speed and the continuity of routine we may well feel that one of the chief causes is fatigue.

FATIGUE

Excitement, mental and muscular work, poor health, regrets, fear, worry, mental conflict, eyestrain, uncomfortable feet and constipation, in fact anything that causes pain or continued discomfort, brings about conditions in the nervous system known as FATIGUE. It is the accumulation of waste products and the exhaustion of reserve nutritive matter in the nerve cell. Ordinarily, fatigue resulting from monotonous activity is repaired by a change to something else. Fatigue of the days work is usually overcome by a night's sleep. But if, day after day, for an extended time, the fatigue becomes excessive, it accumulates and continues to destroy nerve cells and Neurosis sets in. If this continues, abnormal conditions such as brain fag, neurasthenia and nervous prostration are likely to develop. If the will power is weakened the power of concentration lessened, and the higher mentality reduced, the mind turns to morbid ideas; fears or phobias develop
