The ear is the organ of hearing. It is also the organ of equilibrium. The ear is subdivided into three major parts: the external ear, middle ear, and internal ear. External Ear The external ear consists of two parts: the auricle and the external acoustic meatus. The

Sensory Receptors involved in Static Equilibrium and Dynamic Equilibrium

Several types of sensory receptors provide information to the brain for the maintenance of equilibrium. The eyes and proprioceptors in joints, tendons, and muscles are important in informing the brain about equilibrium and the position and movement of body parts. However, unique receptors in the internal ear

The Structure of the Eye and the Functions of these Accessory Structures.

Vision is one of the most important senses supplying information to the brain. The sensory receptors for light stimuli are located within the eyes (or eyeballs), the organs of vision. The eyes are located within the orbits, where they are protected by seven skull bones Connective tissues

Mouth and Esophageal Motility

Mastication, or chewing, mixes food with salivary mucus. This action subdivides food and exposes ingested starch to salivary amylase to begin the digestive process. Mastication is not essential for normal GI function but facilitates the process. Swallowing propels food from the mouth into the esophagus. The initiation

Homeostasis Regulation – Positive and Negative Feedback Mechanism

Homeostasis, a term presented by W. B. Cannon, describes the mechanism by which the constancy of the internal environment is maintained and ensured Homeostasis is the maintenance of a fairly steady internal environment by self-regulating physiological processes Homeostasis keeps body temperature and the structure of blood and
