Special visceral movements include: striated muscles of the throat.
Exercise, vocal cord movement, etc. General visceral movements include: gland secretion, smooth muscle.
myocardial exercise, etc. Special visceral motor nuclei mainly include oculomotor nerve nuclei, trochlear nerve nuclei, abducens nerve nuclei, and trigeminal nerves.
Motor nucleus, facial nerve nucleus, hypoglossal nerve nucleus, etc.
1. Whether it is controlled by will.
Generally, internal organs are not controlled by their own will, such as the movement of the heart muscle, the movement of smooth muscle.
The so-called special is compared with the general, and most of the motor functions of the internal organs are voluntary, uncontrolled activities such as gland secretion, smooth muscle and myocardial movements.
2. The motor function is different.
For some internal organs, there are also some different motor functions, such as vocal cord movement, swallowing movement, etc.
-
It is because the sternocleidomastoid muscle, facial muscle, etc. are transformed from the parotid arch in the embryonic stage, and the parotid arch itself belongs to the internal organs with respiratory functions, although in humans, it has evolved into non-visceral structures such as skeletal muscle, but the origin comes from the internal organs, so it is called special internal organs.
-
The only special splanchnic nuclei are the motor nucleus of the trigeminal nerve, the facial nucleus, the suspicious nucleus, and the accessory nucleus.
Oculomotor nuclei, trochlear nuclei, hypoglossal nucleus, and abducens nucleus are all general somatic motor nuclei.
Don't talk nonsense.
-
I think what's special is that you can control yourself, which is generally not under your own control.
-
It is a special visceral motor nucleus, mainly including oculomotor nerve nucleus, trochlear nerve nucleus, abducens nerve nucleus, trigeminal nerve motor nucleus, facial nerve nucleus, hypoglossal nerve nucleus, etc.
-
It refers to the movement of internal organs, cardiovascular and the secretion of glands, which are usually not controlled by the human will and are involuntary.
Or are you asking about visceral motor nerves, including sympathetic and parasympathetic nerves.
The difference between sympathetic and parasympathetic is that the central part is different, the lower center of the sympathetic nerve is located in the lateral angle of the first thoracic segment to the third lumbar segment of the spinal cord, and the lower center of the parasympathetic nerve is located in the sacral part of the brainstem and spinal cord. The location of the peripheral ganglia is different, and the preganglionic fibers of the sympathetic nerve emanating from the lateral horns leave the spinal nerve along with the anterior root and spinal nerve out of the intervertebral foramen and reach the sympathetic ganglia.
After a portion of neurons are exchanged within the ganglion, the postganglionic fibers leave the sympathetic trunk and return to the spinal nerves, where they are distributed with the spinal nerves to the blood vessels, sweat glands, and erector pili muscles of the limbs and body walls. After most of the preganglionic fibers exchange neurons within the sympathetic trunk, the postganglionic fibers no longer join the spinal nerves and form plexuses around the arteries, which are distributed with the arteries to the organs and glands of the head, neck, and thoracic and abdominal cavities. The parasympathetic nerve from the center of the preganglionic fibers in the parasympathetic ganglion exchange neurons, postganglionic fibers are distributed to smooth muscle, myocardium and glands, the parasympathetic ganglia are generally near the organ or in the organ wall, the postganglionic fiber is short.
Both have different effects on the same organ. When the sympathetic nerve is excited, the abdominal viscera and peripheral blood vessels constrict, and the heartbeat accelerates and strengthens; bronchial smooth muscle dilation; inhibition of gastrointestinal motility and gastric secretion; hypermetabolism; mydriasis, etc. When parasympathetic is excited, the heartbeat slows and decreases; bronchial smooth muscle contraction; Gastrointestinal motility strengthens and promotes the secretion of digestive juices; miosis, etc.
In general, internal organs have sympathetic and parasympathetic dual innervation, and the action of these two nerves on the same organ is usually antagonistic, but the activities of the two types of nerves in the whole are opposite, unified and coordinated with each other. When the body is in a calm state, the excitation of the parasympathetic nerve is dominant, which is conducive to the digestion and absorption of nutrients and the replenishment of energy, and is conducive to the protection of the body. When exercising vigorously or in an unfavorable environment, the activity of the sympathetic nervous system is strengthened, mobilizing the potential of many organs of the body to improve the ability to adapt to rapid changes in the environment, and maintain the relative stability of the internal environment.

Engaging in sports can make people feel comfortable and happy, and regulate some unhealthy emotions and psychology of people. American psychologists have found that running can successfully reduce the anxiety and nervousness of college students during exams. It has also been found that people with nervous irritability can relax their nervousness by taking a few minutes of walking or engaging in recreational sports.
At the same time, through training, overcoming difficulties, and cultivating a strong will and a spirit of teamwork, we can correct bad or unsound personalities such as depression, depression, selfishness, and looseness. Sports are good for mental health! 1. Participating in recreational and sports activities is beneficial to overcoming psychological barriers.
2. Participating in recreational and sports activities can help relieve tension. 3. Sports competitions help with psychological catharsis.

In fact, sports will have more or less wear and tear on the internal organs, of course, compared with the benefits of exercise for young people, which losses can be ignored, but it still depends on your age and physical condition, it is recommended to play tai chi or swimming.
Friend; The exercise of the internal organs is also the lung capacity; Other organs rely on eating to exercise and maintain; Strenuous exercise can exercise lung capacity; Friend; Not having good physical fitness; There is no good insider to teach you; It's best not to practice qigong; It's easy to deviate; Hope you understand; ok;
Exercise with high intensity, high amount of exercise, and short duration is generally anaerobic exercise. >>>More
Follow the steps below and stretch your body slowly until you feel your muscles tighten. When you feel pain, don't deadlift the ligaments and don't jump in case the muscles are strained. During each stretch, hold for 10-20 seconds and breathe evenly. >>>More
