What are the cranial nerves that connect to the brainstem? Where is it connected to the brainstem?

The brainstem is located below the brain, between the spinal cord and the diencephalon, and is a smaller part of the central nervous system in an irregular columnar shape. The brainstem is composed of three parts: the medulla oblongata, the pons, and the midbrain. The medulla oblongata is connected to the spinal cord below.

The cranial nerves connected to the brainstem include oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve, vagus nerve, accessory nerve, and hypoglossal nerve. The gray matter within the brainstem is dispersed into clumps of gray matter of varying sizes.

The nucleus is involved in receiving the activity of the organs innervated by afferent and efferent impulses in the periphery, as well as in the conduction of ascending and descending tracts. In addition, in the medulla oblongata and pons, there are reflex centers that regulate important physiological activities such as cardiovascular movement, breathing, swallowing, and vomiting. If these centers are damaged, it can cause serious disruptions to the heart rate, blood pressure, and even life-threatening.

The midbrain has oculomotor nerve, trochlear nerve, etc

The pons of the pons are the trigeminal nerve, abducens nerve, facial nerve, and vestibulocochlear nerve.

The medulla oblongata has glossopharyngeal nerves, vagus nerves, hypoglossal nerves, and accessory nerves.

The general rule is one sniff, two sights, three eye movements, four slides, five forks and six abductions. Seven sides, eight snails, nine tongues, ten labyrinthalms, eleven pairs, twelve sublinguals.

Oculomotor and trochlear connect to the midbrain.

Trigeminal, spread, face, vestibular cochlea connect the pons.

Glossopharyngeal, vagus, accessory, sublingual connection to the medulla oblongata.

The surface of the brainstem is connected to the 3rd and 12th pairs of cranial nerves.

Cranial nerves connected to the midbrain: the third pair of oculomotor nerves exits from the interankle fossa of the midbrain; The 4th pair of trochlear nerves pass from below the dorsal hypothalamus of the midbrain.

Cranial nerve connected to pons: a 5th pair of trigeminal nerves is attached where the ventral surface of the pons begins to narrow; In the medullary pontine sulcus, the 6th pair of abducens nerve, the 7th pair of facial nerves, and the 8th pair of vestibulocochlear nerves are medial to lateral.

Cranial nerves connected to the medulla oblongata: in the posterolateral medulla sulcus, from top to bottom are the 9th pair of glossopharyngeal nerves, the 10th pair of vagus nerves, and the 11th pair of accessory nerves; The twelfth pair of hypoglossal nerves passes through the anterolateral sulcus.

There are many nerves that emanate from the surface of the brainstem, and these nerves innervate the body's activities and thoughts.

What are the emotions coming from the surface of which brainstem? Short-answer questions? Uh-huh, my nerves are uh, all over the place, and then that it's density. His revenge also covers a wide area, well, try not to uh, let the brain be hit or traumatized.

The nerves on the surface are now very active, so they have to be drunk.

There are 12 pairs of cranial nerves, and you can memorize it.

What are the benefits of nerves emanating from the surface of the stick? Short-answer questions? Simple. It's easy to take a look!

Analysis: Brainstem: includes medulla, pons, and midbrain. There are also people who include diencephalon.

Gross structure of the brainstem The dorsal side of the cross-section of the midbrain contains the midbrain aqueduct, which is surrounded by gray matter, which is quadruplacent on the dorsal side and the cerebral foot on the ventral side. The brain foot is divided into two parts, the dorsal tegment and the ventral soles, by the substantia nigra. The pons is divided into two parts: the basal and the cover.

The basal base is ventral and contains a large number of transverse fibers, and the tegment is a direct continuation of the medulla oblongata dorsally. The medulla oblongata is covered except for the pyramid.

The internal structure of the brainstem retains the general structure of the spinal cord in many respects, such as gray and white matter and many ascending and descending fibers. But the brainstem has a number of features compared to the spinal cord: the first cranial nerve nucleus appears, both sensory and motil.

There are many motor and sensory transit nuclei, such as the red nucleus, which receives fibers from the cerebral cortex and emits fibers to project to the spinal cord to control movement, which is a motor transfer nucleus. The thin bundle nucleus and the cuneiform nucleus receive afferent fibers from the dorsal side of the spinal cord and project fibers to the thalamus, which belongs to the sensory middle transfer nucleus. Due to the continuous development of the brain and cerebellum, the connection between the two through the brainstem is also developing, especially the base of the pons, which is an important transit station for the brain-brain-cerebellar pathway.

Appearance of brainstem reticular structures.

The function of the brainstem is closely related to its location and its connection to the various parts of the central nervous system. The brainstem is first and foremost a transit point for many ascending and descending neural pathways, such as the spinal cord to the cerebellum, cerebellum to spinal cord, spinal cord to diencephalon, and brain to spinal cord. The second is that the brainstem controls many of the sensory and motor functions of the head and face, which is related to the cranial nerve from which it emanates.

Thirdly, it is the location of many important functional centers, such as respiration, heart rate, and blood pressure maintenance, which are controlled by the relevant centers of the brainstem. In the past, these parts were called life centers.

The brainstem is also associated with the maintenance of posture and the righting reflex in animals. The brainstem reticular structure also plays an important role in maintaining muscle tone and maintaining brain excitability.

Cranial nerves from the brainstem The brainstem gives rise to cranial nerves, which have three types of properties: sensory, motor, and mixed. According to the structure of cranial nerve distribution, cranial nerve fiber components can be divided into the following seven categories (see annex).

Among these 7 categories, general visceral afferents and efferents, general somatic afferents and somatic afferents are basically similar to the distribution of spinal nerves; Afferent fibers from the inner ear are called special somatic afferent fibers. The afferent fibers of the taste buds in the oral cavity are called special visceral afferent fibers. Some muscles of the head and neck are derived from the high arch of the parotid arch during the embryonic period, so the efferent fibers that innervate these muscles are called special visceral efferent fibers.

Although the location of the nuclei that give rise to the first cranial nerve varies, a closer look shows that the sensory cranial nuclei are relatively close to the outside, due to the expansion of the fourth ventricle, which corresponds to the lateral extension of the wing plate of the neural tube. The motor cranial nucleus is closer to the medial.

The brain mainly includes the left and right cerebral hemispheres and is the highest part of the central nervous system. To put it simply, the brain controls all human cognition, perception, emotion, memory, and other mental activities. See for details.

The function of the cerebellum is simply to maintain the balance of the body. Through its rich afferent and efferent connections with the brain, brainstem, and spinal cord, the cerebellum is involved in the regulation of somatic balance and muscle tone (muscle tone), as well as the coordination of voluntary movements.

The function of the brainstem is mainly to maintain the life of an individual, including important physiological functions such as heartbeat, breathing, digestion, body temperature, and sleep, which are all related to the function of the brainstem. If the brain stem is damaged, the person is likely not to survive.
