It consists of the cupola which is a gelatinous wedge shaped structure running fully across the cross-section of the ampula. Into the thick end of this wedge projects … Continue reading Physiology of balance and equilibrium →

Pancreas is a mixed type of gland consisting of two parts: Exocrine part and Endocrine part. The bulk of the Pancreas consists of glandular acini which secrete a powerful digestive juice into the gut. This is the exocrine part of the pancreas.

The first step in Physiology of Vision is retinal image formation and activation of Photoreceptors. The resulting nerve impulses are then passed to the visual areas of the cerebral cortex. Retinal … Continue reading What is the Physiology of Vision? →
