Physiology – the study of how living organisms p0erform the vital functions. Microscopic Anatomy – study of structures that can not be seen by the naked eye. Cytology – analyzes the internal structure of individual cells. Histology – the study of tissues Gross Anatomy – considers features visible with the unaided eye. Surface Anatomy – refers to the study of general form and superficial markings. Regional anatomy – considers all of the superficial and internal features in a specific region

Melanin protects the cell nucleus from the destructive effects of UV radiation Langerhans cells: arise from the bone marrow and migrate to the epidermis and other areas of the body containing stratified squamous epithelial tissue. Merkel cells: present in small numbers at the epidermal-dermal junction. Associated with a disc-like ending of a sensory nerve fiber‚ called a Merkel disc‚ which functions as a sensory receptor.

be strong to support the animal’s weight. Typically‚ the weight-bearing muscles have a higher amount of connective tissue because they contain strong protein. The toughness of meat is contributed by the number of cross-linked chains per volume of meat explains a large amount of tenderness variation‚ produced by muscle type‚ animal age‚ type‚ and sex in different species. But connective tissue in meat is not desirable as it is tough and doesn’t usually result in a positive eating experience. During

The normal pulp is pink‚ coherent soft tissue is noted‚ dependent on its normal hard dentin for protection. Dentin and pulp are embryologically‚ histologically‚ and functionally the same tissue and therefore are considered as a complex. Both dentin and pulp have a common origin from the dental papilla It
