1. The distribution of covering epithelium?
2. The difference between exocrine and endocrine glands?
3. Which specializations could be seen at the free, basal, and lateral surfaces of epithelia？
4. Please preview general connective tissue.
Endocrine gland is a gland whose secretions (called hormones) are collected by the blood and reach the tissues through the circulation. ... Exocrine gland is a gland whose secretions are released externally through ducts.
Apical surface specializations.
Lateral surface specializations.
Junctions and basal surface specializations.
General connective tissue is either loose, or dense, depending on the arrangement of the fibres. The cells sit in a matrix made up of glycoproteins, fibrous proteins and glycosoaminoglycans, which have been secreted by the fibroblasts, and the major component of the matrix
