Q14:In anatomy, the epigastrium (or epigastric region) is the upper central region of the abdomen. It is located between the costal margins and the subcostal plane.

The epigastrium is one of the nine regions of the abdomen, along with the right and left hypochondria, right and left lateral regions (lumbar areas or flanks), right and left inguinal regions (or fossae), and the umbilical and pubic regions.

During breathing the diaphragm contracts and flattens, displacing the viscera and producing an outward movement of the upper abdominal wall (epigastric region). It is a convergence of the diaphragm and the abdominals, so that "when both sets of muscles (diaphragm and abdominals) tense, the epigastrium pushes forward".Therefore, the epigastric region is not a muscle nor is it an organ, but it is a zone of activity where the actions of the rectus abdominis and the diaphragm produce an outward bulging of the upper abdominal wall. It is also the spot where the Heimlich Maneuver is able to produce a rapid and forceful exhalation of breath.

Q15:Exocrine glands are glands that secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, prostate and mucous.

Q16:A)Melanocyte, specialized skin cell that produces the protective skin-darkening pigment melanin. Birds and mammals possess these pigment cells, which are found mainly in the epidermis, though they occur elsewhere e.g., in the matrix of the hair.

Q17: A) Centrioles are especially important during mitosis.

There are two main functions of centrioles that we will focus on. The main function of the centriole is to help with cell division in animal cells. The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis).

Q18: A) Human body has two types of sweat glands:eccrine and apocrine.

Eccrine glands occur over most of your body and open directly onto the surface of your skin.

Apocrine glands open into the hair follicle, leading to the surface of the skin.
