Special sensory receptors are also placed in various locations throughout the body to send signals to the brain for the sense of smell, taste, vision, hearing, and equilibrium. When the body experiences a stimulus such as taste or smell an electrical signal or nerve impulse is fired. The electrical impulse is then transmitted in the nervous system pathway to the brain, the brain then perceives of the stimulus. Different types of sensory receptors are all over the body and have various different functions. Paciniam corpuscle for instance is a general sense organ which allows us to perceive the sense of pressure.

Specialized receptors found near the point of a junction of a joint or muscle tissue are called propriocepters. When these receptors are stimulated, they provide us with information concerning the position or movement of the appendages of the body. When golgi tendon receptors are stimulated, they provide the body with information concerning the length and extent of the contraction and tension in our muscles. These are the two main examples of proprioceptors in the body.

The upper respiratory system is comprised of the nose, larynx, and pharynx, and the lower respiratory system is treachea, bronchi, and finally the lungs. A common medical term that you would see is URI which stands for upper Respiratory Infection, the common cold in other words. A more sever form of the common cold once fluid has accumulated in the lungs is called pneumonia. The body fights and expels the fluid in the lungs with cilia which moves the mucus along the lining of the trachea. An expectorant would aid the body in riding itself of the fluid.

The nose has a lining which separates the right and left nasal cavities called the septum. Once the air flows into the nose the structures which assist in humidifying the air that we breath is the lacrimal sacs and conchae. The lacrimal sacs or tear ducts are used when someone is crying and the person’s nose gets runny.  The conchae are structures that are inside the nasal cavities that allow air to be warmed and humidified. Then the air moves on to the pharynx another word for the throat. Pass the the throat is the voice box or larynx which also has cartilage known as the adams apple in males. Females also have an adams apple but it’s not as pronounced as in males. The interior portion of the larynx houses the vocal cord and as air passes the cord it strums them making sounds much like a whistle or trumpet using the lips of the player.
