| nucleus proprius | The Nucleus proprius is a layer of the spinal cord adjacent to the substantia gelatinosa. Nucleus proprius constitutes the bulk of the dorsal horn and receives inputs from the dorsal root ganglions that carry sensory information, such as light touch, as well as pain and temperature information. Cells in this nucleus project to deeper laminae of the spinal cord, to the posterior column nuclei, and to other supraspinal relay centers including the midbrain, thalamus, and hypothalamus. Rexed laminae III, IV, and V make up the nucleus proprius [Wikipedia: http://en.wikipedia.org/wiki/Nucleus_proprius_of_spinal_cord]. | — |
| nucleus thoracicus | Clarke's column (column of Clarke, dorsal nucleus, posterior thoracic nucleus) is a group of interneurons found in Lamina VII, also known as the intermediate zone, of the spinal cord [Wikipedia: http://en.wikipedia.org/wiki/Posterior_thoracic_nucleus]. | posterior thoracic nucleus; Clarke's column; column of Clarke; dorsal nucleus; posterior thoracic nucleus |
| optic nerve | The optic nerve is the nerve that connects the eye to the brain and carries the impulses formed by the retina to the visual cortex of the brain [Brenda]. | — |
| ovary | One of the typically paired essential female reproductive organs that produce eggs and in vertebrates female sex hormones [Brenda]. | — |
| parotid gland | Either of a pair of large serous salivary glands situated below and in front of the ear [Brenda]. | — |
| penis | A male organ of copulation that in male mammals including humans usually functions as the channel by which urine leaves the body [Brenda]. | — |
| phrenic nucleus | A nucleus comprised of motor neurones located in medial areas of the ventral horn of the spinal cord from about C3 to C6; axons of neurones in this nucleus innervate the diaphragm [Mondofacto: http://www.mondofacto.com/facts/dictionary?phrenic+nucleus]. | — |
| placenta | The vascular organ in mammals except monotremes and marsupials that unites the fetus to the maternal uterus and mediates its metabolic exchanges through a more or less intimate association of uterine mucosal with chorionic and usually allantoic tissues; also: an analogous organ in another animal [Brenda]. | — |
| prefrontal cortex | The prefrontal cortex is the anterior part of the frontal lobes of the brain, lying in front of the motor and premotor areas [Brenda]. | — |
| prostate | The prostate (from Greek ÏÏοÏÏάÏÎ·Ï - prostates, literally "one who stands before", "protector", "guardian") is a compound tubuloalveolar exocrine gland of the male reproductive system in most mammals [Wikipedia: http://en.wikipedia.org/wiki/Prostate]. | — |
| renal vasculature | The renal arteries normally arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle with the aorta [Wikipedia: http://en.wikipedia.org/wiki/Renal_artery]. | renal artery |
| retina | The sensory membrane that lines the eye, is composed of several layers including one containing the rods and cones, and functions as the immediate instrument of vision by receiving the image formed by the lens and converting it into chemical and nervous signals which reach the brain by way of the optic nerve [Brenda]. | — |
| retrodorsolateral column | — | — |
| sacral parasympathetic nucleus | — | — |
| sclera | The tough white outer coat of the eyeball, covering approximately the posterior five-sixths of its surface, and continuous anteriorly with the cornea and posteriorly with the external sheath of the optic nerve [Brenda]. | — |
| spinal ganglion | A ganglion on the dorsal root of each spinal nerve that is one of a series of ganglia lodging cell bodies of sensory neurons [Brenda]. | — |
| sublingual gland | Gland situated or administered under the tongue; the smallest of the three salivary glands, occurring in pairs, predominantly mucous in type, and draining into the oral cavity through 10 to 30 sublingual ducts [Brenda]. | — |
| submandibular gland | One of the three chief, paired salivary glands, predominantly serous, lying partly above and partly below the posterior half of the base of the mandible [Brenda]. | — |
| substantia gelatinosa | The apex of the posterior horn of the gray matter of the spinal cord is capped by a V-shaped or crescentic mass of translucent, gelatinous neuroglia, termed the substantia gelatinosa of Rolando (or SGR) (or gelatinous substance of posterior horn of spinal cord), which contains both neuroglia cells, and small nerve cells. The gelatinous appearance is due to a very low concentration of myelinated fibers.It is named after Luigi Rolando. It corresponds to Rexed lamina II [Wikipedia: http://en.wikipedia.org/wiki/Substantia_gelatinosa_of_Rolando]. | substantia gelatinosa of Rolando; gelatinous substance of posterior horn of spinal cord |
| synapse | In the nervous system, a synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell (neural or otherwise). The word "synapse" comes from "synaptein", which Sir Charles Scott Sherrington and colleagues coined from the Greek "syn-" ("together") and "haptein" ("to clasp") [Wikipedia: http://en.wikipedia.org/wiki/Synapse]. | — |
| testis | A typically paired male reproductive gland that produces sperm and that in most mammals is contained within the scrotum at sexual maturity [Brenda]. | — |
| trabecular meshwork | The trabecular meshwork is an area of tissue in the eye located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea) [Wikipedia: http://en.wikipedia.org/wiki/Trabecular_meshwork]. | — |
| tract | A neural pathway, neural tract, or neural face, connects one part of the nervous system with another and usually consists of bundles of elongated, myelin-insulated neurons, known collectively as white matter. Neural pathways serve to connect relatively distant areas of the brain or nervous system, compared to the local communication of grey matter [Wikipedia: http://en.wikipedia.org/wiki/Neural_pathway]. | neural pathway; neural tract; neural face |
| tympanum | The major portion of the middle ear (auris media), consisting of a narrow air-filled cavity in the temporal bone that contains the auditory ossicles. It communicates with the mastoid air cells and the mastoid antrum via the aditus and with the nasopharynx via the auditory tube. The middle ear and the tympanic cavity were formerly regarded as being synonymous [Brenda]. | — |
| umbilical cord | A cord arising from the navel that connects the fetus with the placenta [Brenda]. | — |
