2022年11月16日 · Floor of the sheep’s brain’s third ventricle – is bounded by the infundibulum, tuber cinerium, and optic chiasma, On the cranial part of the third ventricle of the sheep brain, you will find the lamina cineria.

On this image, the dura mater has been completely removed, you can still see the optic chiasma but the pituitary gland is missing. The infundibulum (pituitary stalk) is now visible in the center. Careful dissection also reveals two other large nerves: the oculomotor nerves (C.2).

Just behind the optic chiasma is a raised area or bump that indicates the infundibulum (also known as the pituitary stalk). This is where the pituitary was attached to (which was probably removed with the dura mater).

Diencephalon includes the following areas/structures: 3rd ventricle, Thalamus (wall of 3rd ventricle), Hypothalamus (floor of 3rd ventricle), Optic chiasm(a), Tuber cinereum, Infundibulum (stalk of pituitary gland), Pituitary gland, and Mammillary body.

By dissecting a sheep brain, students can compare it to human brains, understanding both the similarities and variations in structures, functions, and organization. 1. Brain Gallery for Photos and Images of Sheep Brains. 2. Sheep Brain Dissection for in-person learning. 3. Google Slides for Virtual Sheep Dissection. No sheep brain needed! 4.

As you lift the pituitary, notice a small, thin tubular structure, the infundibulum or infundibular stalk, which joins the pituitary to the base of the brain. It is located on the midline, anterior to the oculomotor nerves.

Just behind the optic chiasma is a raised area or bump that indicates the infundibulum (also known as the pituitary stalk). This is where the pituitary was attached to (which was probably removed with the dura mater). Oculomotor nerves may be …

Sheep brain dissection is a mainstay of many neuroscience and biological psychology lab courses. Sheep brain dissection is relatively easy and requires only the brains, surgical gloves, and a large, sharp knife without serrations to provide a valuable learning experience.

The brain of the sheep is useful for study because its anatomy is similar to human brain anatomy. Although exact proportions (and names) sometimes differ, every structure you will identify in the sheep brain corresponds to a homologous structure, usually with the same name, in humans.

A drawing of the brain with the parts unlabeled. Students can practice naming the parts of the brain, then check their answers with the provided key.
