The hypoglossal nerve is the twelfth paired cranial nerve.. Its name is derived from ancient Greek, hypo meaning under, and glossal meaning tongue.The nerve has a purely somatic motor function, innervating all the extrinsic and intrinsic muscles of the tongue (except the palatoglossus, innervated by vagus nerve).. The secretions of the uterine tube nourish both ovum and spermatozoa. A testicle or testis (plural testes) is the male reproductive gland or gonad in all bilaterians, including humans.It is homologous to the female ovary.The functions of the testes are to produce both sperm and androgens, primarily testosterone.Testosterone release is controlled by the anterior pituitary luteinizing hormone, whereas sperm production is controlled both by the The male reproductive system is responsible for sexual function, human reproduction, and urination. The female sex organs consist of both internal and external genitalia. Neuron. and iliac nodes that surround the iliac vessels. Structure. Jessica E. McLaughlin , MD, Medical University of South Carolina A rich supply of blood vessels gives the labia minora a pink color. In our entire urinary system series, the urinary bladder The main arterial supply to the testes and epididymis is via the paired testicular arteries, which arise directly from the abdominal aorta.They descend down the abdomen, and pass into the scrotum via the inguinal canal, contained within the spermatic cord. it is often considered together with the reproductive system as the urogenital system. The development of these reproductive organs begins at an early stage in the embryo. They control the shape of the rima glottidis (opening between the vocal folds and the arytenoid cartilages), and the length and tension of the vocal folds.. All the intrinsic muscles of the larynx (except the cricothyroid) are innervated by the inferior laryngeal nerve Erection of the penis is stimulated by the parasympathetic nerve innervations, and the blood supply for the penis is from the penile artery. Neuropathy. Updated on September 24, 2017. abducent nerve The sixth cranial nerve; it stimulates a muscle of the eyeball and two skeletal muscles that move the nictitating membrane across the eyeball. It is a rich source for the amino acid taurine, which is used for cardiac health and nerve transmission. Anatomical Position. It is innervated by the dorsal nerve of the clitoris, a terminal branch of the pudendal nerve.

The spleen is an organ found in almost all vertebrates.Similar in structure to a large lymph node, it acts primarily as a blood filter.The word spleen comes from Ancient Greek (spln).. Intrinsic Muscles. The reproductive system is a collection of internal and external sex organs which work together for the purpose of sexual reproduction.. The urinary bladder and urethra are pelvic urinary organs whose respective functions are to store and expel urine outside of the body in the act of micturition (urination). Cells that propagate information via electrochemical impulses. This is an article covering the anatomy of the different arteries which supply the spinal cord with oxygenated blood. The prostate function is to produce fluid secreted into the urethra during ejaculation. Level of Decussation of the Medial Lemniscus. The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized Oyster meat: totally natural, oyster extract is excellent for mens reproductive health and endurance.

The female reproductive system is a complicated but fascinating subject. AJOG's Editors have active research programs and, on occasion, publish work in the Journal. Parasympathetic nerve supply arises through three primary areas: Certain cranial nerves in the cranium, namely the preganglionic parasympathetic nerves (CN III, CN VII, CN IX and CN X) usually arise from specific nuclei in the central nervous system The Journal of Pediatrics is an international peer-reviewed journal that advances pediatric research and serves as a practical guide for pediatricians who manage health and diagnose and treat disorders in infants, children, and adolescents.The Journal publishes original work based on standards of excellence and expert review. The intrinsic laryngeal muscles act on the individual components of the larynx. The pancreas is an oblong-shaped organ positioned at the level of the transpyloric plane (L1). There are some terms that are specifically used in the description of embryology, which have the potential to further complicate an already complex subject!. reproductive system of male & female lecture notes for Nursing students . The urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra.The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.The urinary tract is the body's drainage system for the Male Reproductive System Anatomy and Physiology. Vascular Supply. With the exception of the tail of the pancreas, it is a retroperitoneal organ, located deep within the upper abdomen in the epigastrium and left hypochondrium regions. The anatomical terms of location are vital to understanding and using anatomy. Historically known as an aphrodisiac, flavonoids in oyster meat have been shown to stimulate the reproductive system. Readily absorbed by brain for healthy function & youthful cognition; Helps maintain crucial synaptic connections between brain cells; Promotes healthy brain cell signaling pathways In each corpus cavernosum, note one or two arteries, the deep arteries slide 286 View Image, that supply the arterioles. A resumed contraction of the smooth muscle in the helicine arterioles leads to detumescence. ; Infundibulum funnel-shaped opening near the ovary to which fimbriae are attached. A medical specialty concerned with the study of the structures, functions, and diseases of the nervous system. Functions The uterine tubes propel the ovum from the ovary to the uterus by peristalsis and ciliary movement. In this article, we shall look at the Editor/authors are masked to the peer review process and editorial decision-making of their own work and are not able to access this work in A nerve problem that causes pain, numbness, tingling, swelling, or muscle weakness in different parts of the body. This level marks the sensory decussation occurs of the medial lemniscus. The male gonads are the testes; they are the source of spermatozoa and also of male sex hormones called androgens.The other genital organs are the epididymides; the ductus, or vasa, deferentia; the seminal vesicles; the ejaculatory ducts; and the penis; as well as certain accessory structures, such as the prostate and the bulbourethral system Endocrine system Digestive system Lymphatic system Male reproductive system Female reproductive system. The spleen plays very important roles in regard to red blood cells (erythrocytes) and the immune system. The glans, a sensitive, bulging ridge of tissue, is located at the distal part of the penis.

Blood and nerve supply and lymphatic drainage are as for the uterus. It is found inferior to the urinary bladder, and is penetrated by the urethra. Anatomical Structure. 32. analogous to the male penis. It is an unwanted condition that can cause increasing pain and lead to permanent nerve damage and erectile dysfunction if not treated promptly. (Fig.5).Purple lines have been used to represent the internal arcuate fibres as they run from the nucleus gracilis and nucleus cuneatus around and anterior to the central gray matter to form the medial lemniscus..
