Terms in Male Reproductive System
Primary Organs are the organs that are used to produce the hormones, sperms and the eggs.
Accessory Organs are the organs involved in conveying and creating the gametes, as well as offering support for the embryo.
Urogenital System is the collective reference of both the excretory and reproductive systems of the vertebrates.
A Mesonephric/Wolffian Duct is a tube that is used to drain the kidney and also can be used as the sperm tube during copulation.
Ureter is an independent duct that is existent in birds and reptiles to drain the waste from the kidney. As such, it is exclusive of the sperm duct.
Uterine Duct/Oviduct is a duct independent of the above tubes that opens into a cloaca. A cloaca is a chamber to which all the intestinal, excretion, and reproductive tubes lead.
Testes-are a site or an organ where the sperms are produced in a male reproductive system.
Seminiferous Tubule is the tubes in which sperms grow and develop after production.
Sustentacular/Sertoli Cells are cells that basically surround the sperms in order to nourish them during growth.
Interstitial Cells are the cells responsible for the production of testosterone that is essentially male sex hormone.
Epididymis is a tube where all the seminiferous tubules lead after passing the vasa efferentia.
Urethra is a duct which is responsible for carrying both the sperms and urinary material.
Seminal Vesicles, Prostate Glands and Bulbourethral Glands are glands in a male reproductive system that produce respective secretions which ultimately make the semen in the male reproduction system.
Terms in Female Reproductive System
Oviduct is a tube also known as the uterine tube and it is used to envelope the ovary.
Follicle is a development of the oocytes contained in the female ovary. They enlarge and burst to release other secondary oocytes.
Uterus is a chamber that is also known as the womb. It is responsible for holding the embryo during its development.
Endometrium is a dense network of the blood vessels and muscular walls which supply the uterus with blood.
Vagina is a muscular tube that receive the male penis during copulation to deposit the sperms.
Cervix is a small opening where the vagina and the womb meet.
Vulva is the external genital which has a fold of a skin and exists in a female human being. It contains two skin folds including the labia majora and labia minora
Clitoris is an erectile organ of a female which is equivalent to the penis in a male.
Hymen is a membrane responsible for the reduction of the vulva in the virgin state. It reduces with time as copulation takes place.
Nervous System Terms
Central Nervous System (CNS) is a part of the nervous system that consists of two critical organs including the brain and the spinal cord.
Peripheral Nervous System (PNS) is a section of the system that consists of ganglia that are not included in the brain or spine.
Nerve net- is the most primitive form of the nervous system that has its neurons dispersed in the form of a thin layer.
Centralization is a form of nervous organization where the neurons are joined in a central integration area.
Cephalization is a situation in which the neurons exist in multiple numbers in a certain section of the body.
Nerve Cords are re-organizations of the neurons in longitudinal clusters.
Brain is expressed as the anterior increment of the CNS.
