The empty follicle continues to function as the corpus luteum, or yellow body. It produces hormones that sustain the egg and help prepare the endometrial lining for implantation if it becomes fertilized. Eventuall, it is reabsorbed by the ovary to be reused in the next cycle through a process known as envolution.
False. The zona pellucida is formed as the primary oocyte within the primordial follicle begins to grow and develop into a secondary follicle.
The corpus luteum is the area from which the mature egg broke free from the ovary during ovulation. The corpus luteum produces progesterone which is responsible for the uterine lining build-up.
No. Hair is dead. Hair follicles are the only alive part of the hair. They're what grow and contribute their dead cells to hair growth.
This structure is likely a dermal sheath, which is composed of both the epidermis (epithelial tissue) and the dermis (connective tissue). Dermal sheaths surround some hair follicles and play a role in supporting and nourishing the hair follicle.
Each hair develops from a group of epidermal cells at the base of a tubelike depression called a hair follicle, which extends from the surface into the dermis and contains the hair root. The epidermal cells at the base are nourished from dermal blood vesssels in a projection of connective tissue at the deep end of the follicle. As these epidermal cells divide and grow, older cells are pushed toward the surface. The cells that move upward and away from the utrient supply become keratinized and die. Their remains constitute the structure of a developing hair shaft that extends away from the skin.
False. The zona pellucida is formed as the primary oocyte within the primordial follicle begins to grow and develop into a secondary follicle.
no.. The normal function of the ovaries is to produce an egg each month. During the process of ovulation, a cyst-like structure called a follicle is formed inside the ovary. The mature follicle ruptures when an egg is released during ovulation. A corpus luteum forms from the empty follicle, and if pregnancy does not occur, the corpus luteum dissolves. Sometimes, however, this process does not conclude appropriately, causing the most common type of ovarian cyst -- functional ovarian cysts.

corpus luteum
The corpus luteum, formed from the remnants of the ovarian follicle after ovulation, is the structure that releases progesterone to increase the vascularity of the uterine lining. Progesterone helps prepare the uterus for potential embryo implantation by promoting a rich blood supply to the endometrium.
The inner lining of a hair follicle is formed by the inner root sheath, which is made up of epithelial tissue. This sheath helps to protect and nourish the growing hair shaft as it develops within the follicle.
According to the NIH, it is called a comedo.
The corpus luteum is the area from which the mature egg broke free from the ovary during ovulation. The corpus luteum produces progesterone which is responsible for the uterine lining build-up.
No. Hair is dead. Hair follicles are the only alive part of the hair. They're what grow and contribute their dead cells to hair growth.
Eggs are formed in the ovaries of female animals, where they develop and mature before being released during ovulation.
It can close the opening of a follicle, causing a white head, blackhead, or acne.
