| 설명 | 시각을 인지하는 신경. 이 신경은 단지 감각신경으로서만 작용한다. 따라서 어떤 사물을 따라 눈을 움직일 수 있는 것은 이 시각신경과는 무관하다(이것은 눈돌림신경(oculomotor nerve)에 의해 가능하다). 또한 시각신경은 고위중추신경계인 뇌에서 직접 분지하므로 손상시 재생은 불가능하며, 이에 대한 치료법은 없다. |

| 설명 | 망막의 구조를 직상검안경(망막을 보기 위해 고안된 검사기구)으로 보면 다음과 같다. 망막에 혈액을 공급하는 망막동맥(retinal artery)과, 다시 혈액을 회수하는 망막정맥(retinal vein)은 다같이 시각신경(optic nerve)과 함께 시각신경구멍(optic foramen)을 통해 망막까지 이르게 된다. 즉, 이들 망막 동, 정맥은 시각신경속에 끼워진 채 망막까지 이르게 된다. 따라서 이들 망막 동, 정맥 주위에 존재하는 시각신경유두는 바로 시각신경의 일부분을 말한다. 빛의 자극을 이해할 수 있는 신호체계로 바꾸는 시각세포는 받아들인 자극을 시각신경에서 분지한 수많은 신경절세포(ganglion cell: 신경전달을 모아서 보다 큰 전달단위로 전해주는 역할을 하며, 망막내에 위치한다)로 전달하게 되고, 이들 신경절세포는 다시 이런 자극들을 모아 시각신경유두로 보내게 되며, 시각신경유두에서부터 신경전달은 뇌까지 진행한다.  |

| optic stalk | The constricted proximal portion of the optic vesicle in the embryo; it develops into the optic nerve. Pineal stalk, the attachment of the pineal body to the roof of the third ventricle; it contains the pineal recess of the third ventricle. Pituitary stalk, a process comprising the tuberal part investing the infundibular stem that attaches the hypophysis to the tuber cinereum at the base of the brain. Yolk stalk, the narrowed connection between the intraembryonic gut and the yolk sac; its walls are splanchnopleure. Synonym: umbilical duct, vitelline duct, vitellointestinal duct. (05 Mar 2000) |

| stalk | A stem. Usually refers to the pituitary stalk that connects the pituitary gland to the hypothalamus. (16 Dec 1997) |
| stalk-eyed | <zoology> Having the eyes raised on a stalk, or peduncle; opposed to sessile-eyed. Said especially of podophthalmous crustaceans. Stalked-eyed crustaceans. <zoology> See Podophthalmia. Source: Websters Dictionary (01 Mar 1998) |
| stalk of epiglottis | The lower end or pedicle of the cartilage of the epiglottis, attached to the superior notch of the thyroid cartilage. Synonym: petiolus epiglottidis. (05 Mar 2000) |
| infundibular stalk | The neural component of the pituitary stalk that contains nerve tracts passing from the hypothalamus to the pars nervosa. Synonym: infundibular stalk. (05 Mar 2000) |
| yolk stalk | A narrow tube present in the early embryo that connects the midgut of the embryo (through the umbilical opening) to the yolk sac outside the embryo. Later in development, the yolk stalk is usually obliterated but a remnants of it may persist, most commonly as a finger-like protrusion from the small intestine known as meckel's diverticulum. Found in 2-4% of people, meckel's diverticulum may become inflamed much like the appendix and require surgical removal. The yolk stalk is also called the umbilical duct, vitelline duct, or oomphalomesenteric duct. (12 Dec 1998) |
| axis, optic | <microscopy> The direction, or directions in an anisotropic crystal along which light is not doubly refracted. (05 Aug 1998) |
| ganglionic layer of optic nerve | <anatomy, nerve> The inner layer of multipolar neurons in the retina consisting of the relatively large neurons that give rise to the fibres of the optic nerve. Synonym: stratum ganglionare nervi optici. (05 Mar 2000) |
| vascular circle of optic nerve | <anatomy, nerve> A network of branches of the short ciliary arteries on the sclera around the point of entrance of the optic nerve. Synonym: circulus vasculosus nervi optici, circulus arteriosus halleri, circulus zinnii, Haller's circle, Zinn's corona, Zinn's vascular circle. (05 Mar 2000) |

| pigment epithelium of optic retina | pigmented part of retina |
| optic stalk |
This begins as a narrow channel that connects the optic cup and the brain, but as development progresses it is invaded by neuronal processes that emanate from the ganglion cells of the retina.
