V. Trigeminal nerve

The trigeminal nerve is the largest of your cranial nerves and has both sensory and motor functions.

How many cranial nerves are in a sheep brain?

Sheep Cranial Nerves. Ventral view of a sheep brain. Cranial nerves are marked with red pics and numerical labels. The myelencephalon, located between the pons and the spinal cord, gives rise to seven of the twelve cranial nerves (VI through XIII).

Which nerve in the sheep was very enlarged compared to the human brain?

how does size of the sheep olfactory bulbs comapre to those of the human? the olfactory bulb is larger in a sheep brain than in the human brain. this larger olfactory bulb allows the sheep to have a stronger sense of smell which is vital to its survival.

Which cranial nerve has the largest distribution?

The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body. It contains somatic and visceral afferent fibers, as well as general and special visceral efferent fibers.

What is the biggest nerve?

The sciatic nerve is the largest and longest nerve in the human body, originating at the base of the spine and running along the back of each leg into the foot.

What is the smallest cranial nerve?

Excerpt. The trochlear nerve is the fourth cranial nerve (CN IV) and one of the ocular motor nerves that controls eye movement. The trochlear nerve, while the smallest of the cranial nerves, has the longest intracranial course as it is the only nerve to have a dorsal exit from the brainstem.

Why is a sheep brain smaller than a human brain?

It also weighs less. A sheep's brain is positioned in a different way than a human is. The cerebellum, which regulates motor function and behaviour, is also less developed in sheep than in humans. Sheep's brain has a more developed olfactory lobe and a smaller frontal lobe than humans.

What is 6th cranial nerve?

Cranial nerve six (CN VI), also known as the abducens nerve, is one of the nerves responsible for the extraocular motor functions of the eye, along with the oculomotor nerve (CN III) and the trochlear nerve (CN IV).

Why are olfactory bulbs larger in sheep?

The sheep cerebellum was much smaller than the human cerebellum. ... The olfactory bulb is larger in a sheep brain than in the human brain. This larger olfactory bulb allows the sheep to have a stronger sense of smell which is vital to its survival.

How do the three parts of the sheep brain stem compare to the human brain stem?

The stem on the sheep is longer in comparison to the human, while the cerebellum is wider in the human compared to the sheep. The cerebellum is more protected in the human brain than the sheep brain.

How is a sheep brain similar to a human brain?

The sheep brain is similar to the human brain in that they both have two brain stems, two optic nerves and two hemispheres; but they differ in size and in functions. 2. The human brain is heavier and longer than a sheep's 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. 4. The smaller, rounded structure at the back of the brain is the cerebellum. The cerebellum has smaller gyri that are roughly parallel to one another.

Which cranial nerve has longest intracranial course?

The fourth cranial nerve (trochlear nerve) has the longest intracranial course; it is the only cranial nerve that has a dorsal exit from the brainstem (figure 1).

What is the largest of the cranial nerves Milady?

The largest of the cranial nerves, also known as the trifacial or trigeminal nerve.
