FAQ: Which Of The Following Glands Can Be Observed On The Ventral Surface Of The Sheep Brain?

What can only be seen in the ventral view of a sheep brain?

Find the pineal gland. The most prominent structure visible on the ventral side of the sheep brain is half of the optic chiasma, which is where the two optic nerves cross over each other and form an “X” shape. You will only see half the structure. You may have removed the optic removed the chiasma with the dura mater.

Which of the following structure attaches the pituitary gland to the brain?

The hypothalamus–pituitary complex is located in the diencephalon of the brain. The hypothalamus and the pituitary gland are connected by a structure called the infundibulum, which contains vasculature and nerve axons.

Which of the following ventricles is found under the corpus callosum?

It is located on the dorsal surface of the brain. Which of the following ventricles is found under the corpus callosum? The lateral ventricles lie side by side under the corpus callosum, separated by the septum pellucidum.

What is the groove indicated by C?

The groove indicated by C is the __________. The central sulcus is the shallow groove that separates the frontal and parietal lobes. Axons from the primary motor cortex project from the frontal lobe to the spinal cord.

Is cerebrospinal fluid is produced within the ventricles?

Cerebrospinal fluid CSF is a clear, watery fluid that fills the ventricles of the brain and the subarachnoid space around the brain and spinal cord. CSF is primarily produced by the choroid plexus of the ventricles (≤70% of the volume); most of it is formed by the choroid plexus of the lateral ventricles.

What is the purpose of dissecting a sheep brain?

A sheep brain is used to teach about memory and where it takes place because its brain structure and functions are similar to the human brain.

What is the most prominent region of a sheep brain?

The most prominent feature of the brain is the cerebrum – which is divided into nearly symmetrical left and right hemispheres by a deep longitudinal fissure.

Which gland is known as master gland?

The pituitary gland is sometimes called the “master” gland of the endocrine system because it controls the functions of many of the other endocrine glands.

Which hormones are released by the hypothalamus?

The hormones produced in the hypothalamus are corticotrophin-releasing hormone, dopamine, growth hormone-releasing hormone, somatostatin, gonadotrophin-releasing hormone and thyrotrophin-releasing hormone.

Why hypothalamus is called master gland?

It’s called the master gland because it regulates the activity of the glands. The hypothalamus sends either hormonal or electrical messages to the pituitary gland. In turn, it releases hormones that carry signals to other glands. The system maintains its own balance.

What is corpus callosum?

The corpus callosum is the primary commissural region of the brain consisting of white matter tracts that connect the left and right cerebral hemispheres.

What connects the third and fourth ventricles?

The cerebral aqueduct connects the third ventricle to the fourth. Within the lateral ventricles, choroid plexus is found in the body, atrium, temporal horn and interventricular foramen. Notice that the cerebral aqueduct is located immediately anterior to the midbrain tectum.

Does the foramen magnum marks the border between the medulla oblongata and spinal cord?

The foramen magnum marks the border between the medulla oblongata and spinal cord. The inferior colliculi are part of the corpora quadrigemina.
