Introduction to methods for understanding the relationship between sexual activity and the nervous system to make sex more exciting

The nervous system is the main skill regulatory system within the human body. Under the unified regulation of the nervous system, various organ systems in the body complete different functions, adapt to changes in the internal and external environment, and maintain the normal progress of life activities.

The basic way for the nervous system to achieve its regulatory function is through reflex activity. For example, when the hand touches the kettle, it immediately retracts. In this process, we call it reflection. The completion of reflex activities requires neural channels. Neural channels can also be referred to as reflex arcs. The reflex arc is composed of five parts: sensory organs, nerves, central nervous system, nerves, and effectors. For example, in the previous example, the skin of the hand is a sensor. When you touch boiling water, you will feel hot. This sensation is transmitted to the nerve center - the cerebral cortex, where the center issues avoidance commands, and through the efferent nerve knife effector - the arm muscles and muscles contract, causing the hand to contract. This process involves five parts, but nerve conduction is very rapid, and this continuous action is almost instantaneous. Of course, this is a relatively simple reflex activity. Sexual activity requires the mobilization of many reflexive activities throughout the body that are not equally involved, so the process is much more complex, but the basic principles are the same.

The neural mechanisms that regulate visceral activity are collectively referred to as the functional nervous system, including two parts: the sympathetic and parasympathetic nerves. Many organs are doubly innervated by sympathetic and parasympathetic nerves, and their effects on the same organ are often opposite. For example, when the parasympathetic nerve is excited, the bladder can shrink the urinary muscles, relax the bladder sphincter, and promote urination. When the sympathetic nervous system is excited, the bladder relaxes the urinary muscles, contracts the sphincter muscles, and inhibits urination.

There are secondary centers that control the activity of vegetative nerves, and primary centers in the spinal cord that regulate vegetative function. Some of the most basic reflex activities in the human body can be completed in the spinal cord center, such as vascular tension reflex, sweating reflex, urination reflex, defecation reflex, erection reflex, etc. The human brain is a high-level center that regulates vegetative functions. If the advanced central nervous system of higher animals is damaged, the motor function of the body will be severely affected, and the vegetative function will also be affected to some extent, losing the ability to fine regulate.

In the early 20th century, Pavlov established the Advanced Neuroactivity Theory through scientific experiments. The basic mode of advanced neural activity is mainly conditioned reflex, which is one of the advanced skills of the brain. Conditional reflexes are acquired during personal development.
