Calculate her total energy needs (TDEE) using all 3 equations discussed (Cunningham, Harris Benedict, and Mifflin St. Jeor). In order to calculate using the Cunningham equation, please use the body fat given and […]

The lumen of kidney tubules

A kidney specimen is presented at medium power and intentionally presented in grey scale without colour to test your skill in critical observation of structure. Identify the tissue that lines the spaces (lumen of kidney tubules) that are indicated by blue triangles. They are all lined with the same type of fissue.

Intercalated discs desmosomes contract gap junctions

Intercalated discs desmosomes contract gap junctions. Cardiocytes are connected by structures called Intercalated discs. They include fascia adherents, actin and myosin filaments attached to plasma membranes, and weld-like structures called the cytoplasms between adjacent cells, which are connected and permit ions to pass from one cell to the next. The movement of ions between adjacent […]
