What is the part of the brain that is an extension of the spinal cord? Explain the relationship between the structure of this department and its functions.

The medulla oblongata is an extension of the spinal cord, contains nuclei that control the autonomic functions of the body (respiration, heart function, digestion).
This department performs the following functions:
1. sensory;
2. conductivity functions;
3. reflex functions.
Touch functions
In this case, the department is responsible for the sensitivity of the face at the receptor level, analyzes the taste and auditory sensations, as well as the perception of vestibular stimuli by the body.
Conductivity Functions
As you know, it is in the oblong section that there are many ascending and descending paths. Thanks to them, this area is able to transmit information to other parts of the brain.
Reflex functions
Reflex functions are of two types: vital; minor. Regardless of the type, these reflex functions appear because the data on the stimulus are transmitted along the nerve branches and fall into the oblong section, which processes and analyzes them. Mechanisms such as sucking, chewing and swallowing arise from the processing of information transmitted through muscle fibers.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
