White adipose tissue is the predominant type of fat in the human body. It can be found beneath the skin (i.e., subcutaneous fat), around internal organs (i.e., visceral fat), and in the central cavity of bones (i.e., bone marrow fat), as well as cushioning various parts of the body. Its main role is to serve as an energy storing reservoir, but ...
The basement membrane is formed by a mixture of molecules, including type IV collagen (i.e., the structural protein found in the basement membrane, the lens of the eye, and the cochlea of the ear) primarily and laminin (i.e., a glycoprotein, or protein that contains oligosaccharide chains). Several other proteins, like nidogen and perlecan, can ...
The mons pubis is located in the lower part of the abdomen, overlying the pubic symphysis, which is the fibrocartilaginous joint that sits between the two pubic bones. It is bounded superiorly by the horizontal pubic hairline and inferiorly by the labia majora and clitoris. The labia majora are the two outer folds of skin that extend downwards ...
The renal system, also known as the urinary system, is made up of the kidneys, ureters, bladder, and urethra. The kidneys, a pair of organs located in the back of the abdominal cavity, filter waste products from the blood in the form of urine. The urine passes down through the ureters, which are muscular tubes connecting the kidneys to the bladder.
The breasts are the most prominent superficial structures in the anterior thoracic wall consisting of glandular tissue and a supporting fibrous and fatty matrix. This glandular tissue, or mammary glands, are found in the subcutaneous tissue overlying the pectoralis major and minor muscles. The amount of fat surrounding this glandular tissue ...
Macrophages are a type of white blood cell that play an important role in the human immune system and carry out various functions including engulfing and digesting microorganisms; clearing out debris and dead cells; and stimulating other cells involved in immune function. Macrophages confer innate immunity, which is typically the first line of ...
Resumen. Mammary glands are organs that produce milk for nursing infants. The mammary gland is composed of lobules, which are clusters of cells that produce milk, and ducts, which are the channels that transport the milk to the nipples. The lobules and ducts are surrounded by a layer of adipose tissue, which provides insulation and helps ...
The space between the two labia minora is known as the vestibule, which is mainly occupied by the vaginal opening, or the vaginal introitus. In individuals who have not yet had sexual intercourse, the introitus is typically covered by a membrane of connective tissue known as the hymen. This tissue is often torn during the first coitus.
The skin or the integumentary system is the largest organ of the body that has many important functions in physiology. It protects the body from infections, helps in thermoregulation, and contains nerve receptors that detect pain, sensation, and pressure. The integumentary system is divided into three major components including the epidermis ...
A somatic reflex is an involuntary response to a stimulus, such as pulling one’s hand away after touching a hot stove. The nervous system is split into the central nervous system (i.e., the brain and spinal cord) and the peripheral nervous system (i.e., nervous system outside of the brain and spinal cord).
