Sound, smell and taste are referred to as the sensory organs of an organism. Sensory organs are vital parts of the body that are needed for the regular functioning of the human body.

The hearing sensation requires an integral and working auditory part of the central nervous system and a functioning ear. The deafness in humans occurs due to the abrupt functioning of the inner ear, and not because of the nerves of the central auditory system. The sound’s perception is given the scientific name of audition. It is type of energy that moves through the water, air and the matter. The waves of sound are perceived by the brain through the nerve cells in the auditory segment of the central nervous system.

The ear is divided into three parts on the basis of its functioning. The function of the outer part of the ear is to amass the sound. The process of amplification takes place in the middle part of the ear. The inner ear is unfilled, entrenched in the temporal bone, the thickest bone of the body. The inner ear’s void channels are filled with liquid. It contains a sensory epithelium that is embedded with hair cells. The minuscule hairs of the cells are filaments of the protein, which emit into the fluid. The audio range of the humans is between 20 Hz and 20 kHz. The cranial nerve's Vestibular Portion is dedicated to the sensory balance and position.

The nose serves as the primary limb for smelling. It is a protrusion in vertebrates which consists of nostrils, or nares, which drive out air for respiration in union with the mouth. Inside the nose lie the sinuses and the olfactory mucosa. The air is passed from the nasal cavity to the pharynx, which is communal with the digestive system and then into the rest of the part of the respiratory system.
