Question

c)
State the location of the following structures:
1) Glandular Epithelium ii) Nucellus
111) Lacteal
iv) Patella
v) Vermiform Appendix​

Answer 1

Answer:

1. Examples of glandular epithelium include the epithelium of the endocrine glands like the pituitary gland at the base of the brain, the pineal gland in the brain, thyroid and parathyroid glands near the larynx (voice box), adrenal glands superior to kidneys, pancreas near the stomach, ovaries in the pelvic cavity, :

2. The megasporangium of a seed-bearing plant, located in the ovule. In angiosperms, it is the central portion of the ovule in which the embryo sac develops. In some cases of apomixis (production of seeds without fertilization), cells of the nucellus develop into an embryo.

3. In the intestine, lymphatic capillaries, or lacteals, are located exclusively in intestinal villi, whereas collecting lymphatic vessels are present in the mesentery. 7 The term gut lymphatics used throughout this review refers to both lacteals in the intestinal villi and lymphatic vessels in the submucosa.

4.The patella is a small bone located in front of the knee joint — where the thighbone (femur) and shinbone (tibia) meet. It protects the knee and connects the muscles in the front of the thigh to the tibia.

5.Vermiform appendix is a part of the digestive tract which lies in right lower quadrant of abdomen. It has a worm-like structure and arises during embryological life from the posteromedial wall of the cecum, about 2 cm below the ileocecal valve [1].
