The General and Special Senses Dr. Ali Ebneshahidi

Special senses detect the sensations of taste, smell, hearing, equilibrium, and sight, only in special sense organs in the head region (a phenomenon known as cephalization ). 5. All senses are detected by sensory receptors, and after integration and processing being done in the central nervous system, motor nerves produce a response.

An Introduction to Special Senses When we refer to the special senses, we are referencing the senses that have specialized organs devoted to them. This generally means taste (the tongue), smell (the nose), vision (the eyes) and hearing (the ears). This module will include some activities and require some research that will help you understand

Auditory & Vestibular Systems

Vestibular sense is a special sense. The sensory apparatus senses head movement and position, as well as gravity. The sensory apparatus is part of the inner ear, and vestibular information is carried to the brainstem via the vestibulocochlear nerve (CN VIII). Vestibular function is important for balance, controlling eye movements

Ear, Canal - Dilation

Ear, Canal Dilation Comment: Dilation of the external ear canal (Figure 1, Figure 2, and Figure 3) is usually secondary occlusion of the ear canal by plugs of sloughed keratin lamellae, cerumen, and necrotic debris that distends the canal. The lining epithelium may be hyperplastic. These findings usually occur in aged animals.
