What is the histology of the prostate gland?

What is the histology of the prostate gland?

The hallmark histological feature of the prostate is the fibromuscular stroma in which there are clusters of smooth muscles mixed with elastic fibers. Surrounded by this mixture of tissue are prostatic glands, which are responsible for the production of approximately 27% of seminal fluid.

What type of epithelium is prostate gland?

The amount of pigment is variable and in this example is particularly abundant. The human prostate glandular epithelium is composed of acini and ducts lined by three types of cells: luminal, basal, and neuroendocrine (see Fig. 1C). The acini have an undulating to papillary appearance in most cases (Fig.

What are the characteristics of the prostate gland?

The prostate is a walnut-sized gland located between the bladder and the penis. The prostate is just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body. The prostate secretes fluid that nourishes and protects sperm.

What is the structure of the prostate gland?

The prostate is a gland of the male reproductive system. It is located in front of the rectum and just below the bladder, the organ that stores urine. It is about the size of a chestnut and somewhat conical in shape, and consists of a base, an apex, an anterior, a posterior and two lateral surfaces.

What is the peripheral zone of the prostate?

The peripheral zone extends posterolaterally around the gland from the apex to the base and represents the most common site in the prostate for developing prostate carcinomas. The central zone surrounds the ejaculatory duct apparatus and makes up the majority of the prostatic base.

What cells are in the prostate gland?

The prostate gland has two generic cell types: epithelial and stromal. Epithelial cells form glands that are composed of the luminal secretory and basal cell types and rare neuroendocrine cells. The stroma surrounding the prostatic glands contains smooth muscle cells and fibroblasts.

What is the function of prostate gland?

The prostate gland is located just below the bladder in men and surrounds the top portion of the tube that drains urine from the bladder (urethra). The prostate’s primary function is to produce the fluid that nourishes and transports sperm (seminal fluid).

What is histological anatomy?

Definition of histology 1 : a branch of anatomy that deals with the minute structure of animal and plant tissues as discernible with the microscope. 2 : tissue structure or organization. Other Words from histology Example Sentences Learn More About histology.

What is the basic histological makeup of the prostate?

The diagram reflects the basic histological makeup of the prostate in axial projection. It is composed of 30% glandular tissue (white) and 70% stromal tissue (pink). The glandular tissue is made up of branching tubuloalveolar glands and the stroma consists of smooth muscle, collagen, elastic tissue and fibrous tissue.

What does the H&E histologic specimen of prostatic gland show?

The H&E histologic specimen is taken at low power and shows the components of the prostatic gland including the glandular tissue, and fibromuscular stroma. In general the glandular tissue comprises 30% of the tissue and the fibromuscular component comprises 70%.

Prostate Gland. The prostate is a set of tubulo-alveolar glands with lumina lined by an epithelium of variable height. The gland contains a stroma containing connective tissue and smooth muscle. The prostate produces a fluid rich in citric acid and proteolytic enzymes that nourish and prevent the coagulation of sperm in the vagina.

What type of epithelium lines the lumen of the prostate?

Generally, they are lined by simple columnar or pseudostratified epithelium. Prostatic concretions (precipitations of prostatic glandular secretions) can also be found in the lumen of prostatic glands and are indicative of the age of the patient, as their frequency increases with age.
