Reflex Tonic Cervical Symmetrical

The tonic cervical symmetrical (rtcs) reflex is a physiological reflex that occurs when receptors in the neck are stimulated. This reflex is one of the most common reflexes in the human body.

The rtcs reflex occurs when the head is bent forward, which causes stretching of the neck muscles and increased pressure in the back of the head. In this case, the muscles located in the back of the neck contract and blood flows away from the head. This leads to a decrease in pressure in the occipital region and a decrease in tension in the neck muscles.

It is important to note that the rtcs reflex is an important element of the circulatory regulation system and allows you to maintain normal pressure in the head. This reflex can also be used to diagnose various diseases associated with circulatory disorders in the brain.

Overall, the rtcs reflex plays an important role in maintaining the health and normal functioning of the human body.

Tonic Cervical Symmetrical Reflex: Fundamentals and Role in Neurophysiology

The tonic cervical symmetrical reflex (R. tonicus cervicalis symmetricus) is a complex neurophysiological mechanism that plays an important role in maintaining posture and coordinating movements of the head and neck. This reflex is one of the key elements of the neuromuscular system of humans and other mammals.

The tonic cervical symmetrical reflex has its roots in the neuromuscular system of the head and neck. It occurs in response to various external and internal stimuli, such as changes in head position, neck movement, or gravity. The main centers for the formation and integration of this reflex are located in the upper part of the spinal cord, where the interaction between sensory and motor neurons occurs.

The main effects of the tonic cervical symmetrical reflex are maintaining balance, keeping the head upright and stabilizing body posture. When the posture of the head and neck changes, sensory receptors in the muscles, tendons and joints transmit information to the central nervous system. This information is processed and integrated, and the motor neurons then fire the correct muscles to compensate for the change in posture and restore balance.

The tonic cervical symmetrical reflex plays an important role in the development and functioning of the motor system. In newborn children, this reflex is not yet fully formed, and with age it becomes more complex and accurate. It interacts with other reflexes and neuromuscular mechanisms such as the oral phase reflexes, asymmetric tonic neck reflex and others to ensure normal development of motor skills.

Violation of the tonic cervical symmetrical reflex can lead to various motor and coordination disorders. Uncontrolled movements of the head and neck, poor balance, and problems maintaining an upright posture may result from a malfunction of this reflex. In such cases, early diagnosis and rehabilitation are important to help patients regain normal reflex function and improve their motor coordination.

In conclusion, the tonic cervical symmetrical reflex is an important element of the neuromuscular system, ensuring correct posture of the head and neck, maintaining balance and coordination of movements. It plays a key role in the development and functioning of the motor system and can be impaired in the case of various motor and coordination disorders. Further research and understanding of this reflex may lead to the development of more effective diagnostic and rehabilitation methods for patients with such disorders.
