23-mar-2017 - Sheep Brain Dissection: pineal body, 4th ventricle, cerebellum, spinal cord, medulla, pons, inferior colliculus, superior colliculus, cerebellar peduncle, cerebral peduncle.

Brain, liver, kidneys, heart, spleen, thymus, pituitary, thyroid (post-fixation), brain (representative regions including cerebrum, cerebellum and pons), spinal cord, proteins and vitamins, provides high-quality feed for sheep, goats and cattle.

Sheep Brain – Inferior (region) (thin layer) (region) (region) (thick layer) (with outer meninges) (without outer meninges) Optic chiasma Exercise 1 – Sheep Brain Anatomy Pia mater Midbrain Dura mater Pituitary gland Mammillary body Medulla oblongata Pons • Compare the sheep brain with the main external regions of the human brain. Identify the cerebrum, brain stem (medulla and pons), and cerebellum. 3 Identify dorsal structures (Figure 20.10). • With the dorsal side up, identify the cerebral hemispheres, gyri, sulci, longitudinal fissure, and transverse fissure. Sheep Brain — Ventral View The pons forms a prominent bridge (white pic) on the ventral surface of this sheep brain.The trigeminal nerve emerges laterally from the pons. Other labeled features are: optic chiasm (green pic), infundibulum (orange), mamillary bodies (red), crus cerebri (yellow), trapezoid body (blue), and pyramid (green).

They're both connected. I'm going to just cut off the peduncle. I'm going to cut the connection. Okay there you go. I just cut, I am cutting off the cerebellum.

Programs Brain Stem - The portion of the brain, consisting of the medulla oblongata, pons. Varolii Cerebellum - The tri-lobed structure of the brain, lying posterior to the pons and 12.

Midbrain, Pons, and Medulla: Anatomy and Syndromes The anatomy of the brainstem is complex. It contains numerous cranial nerve nuclei and is traversed by multiple tracts between the brain and spinal cord. Improved MRI resolution now allows the radiologist to identify a higher level of anatomic detail, but an un-

The pons contains nerves and nerve tracts (pathways) that integrate brain functions such as movement and sensory messages between the brain and the body. The pons also coordinates balance in the head, neck, and body and plays a primary role in eye movement, sleeping, dreaming, digestion, swallowing, breathing, and the heartbeat. Goal: We will compare sheep brain structures with human brain structures. Compared to human cerebrum a human’s olfactory bulb is much shorter than sheep olfactory bulbs compared to the sheep cerebrum.

Place the brain with the cerebrum facing up. 2. Use a scalpel to slice through the brain along the center line, starting at the cerebrum and going down through the cerebellum, spinal cord, medulla, and pons. 3.

Gyrus - a ridge or fold between two clefts on the cerebral surface in the brain. Sulcus - a groove or furrow, especially one on the surface of the brain. Pons -Connects the cerebellum to the nervous system.

They make it possible for these structures to send messages — including sensory and motor information — … The MYELENCEPHALON extends from just behind the pons to the beginning of the spinal cord, roughly where the pyramidal tract fibres begin to cross. The Cranial Nerves: The cranial nerves provide sensory input to the brain from the visual, acoustic, gustatory and olfactory sensory organs.

1. Obtain a sheep brain dissection chart from your teacher. 2. Working in a group of two or three, select a whole sheep brain. Lay the brain on the dissecting tray to view the external surface. 3. Identify the external structures indicated below on the brain. Then label the external anatomy diagram with all the structures.

get an idea of what the brain looks like Observation: External Anatomy 1. You'll need a preserved sheep brain for the dissection. Set the brain down so the flatter side, with the white spinal cord at one end, rests on the dissection pan . Notice that the brain has two halves, or hemispheres.

While a human brain has more of a rounded shape, a sheep’s brain is elongated.

The human brain is rounded, whereas the sheep’s brain is elongated in shape. 4. The human brain has a larger frontal lobe than the sheep’s brain. 5.
