The Nervous System and its Divisions

The nervous system is a complex network of cells and tissues that transmit signals between different parts of the body. It is responsible for coordinating and controlling bodily functions. The nervous system can be divided into several divisions, including the sympathetic nervous system, parasympathetic nervous system, somatic nervous system, and autonomic nervous system.

Activation of the Nervous System during Activity

During active periods, the sympathetic nervous system is primarily responsible for initiating and maintaining the body's response. The sympathetic nervous system is part of the autonomic nervous system and is often referred to as the "fight or flight" response. It prepares the body for action by increasing heart rate, dilating blood vessels, and releasing stress hormones like adrenaline.

Interconnection of the Nervous System with Other Systems

The nervous system is interconnected with various other systems in the body. It works in coordination with the musculoskeletal system (also known as the skeletal system) and the endocrine system.

The musculoskeletal system consists of bones, muscles, and joints, and it is responsible for movement and support. The nervous system plays a crucial role in controlling and coordinating muscle contractions, allowing us to move and perform various activities.

The endocrine system, on the other hand, is responsible for producing and releasing hormones into the bloodstream. The nervous system and the endocrine system work together to regulate and maintain various bodily functions, including growth, metabolism, and reproduction.

Regulation of Activity by the Autonomic Nervous System

The autonomic nervous system, which includes the sympathetic and parasympathetic divisions, regulates the activity of internal organs and glands. It controls involuntary functions such as heart rate, digestion, and respiration.

The sympathetic division of the autonomic nervous system is responsible for activating the body's "fight or flight" response, as mentioned earlier. It increases heart rate, dilates blood vessels, and redirects blood flow to the muscles, preparing the body for physical activity or stress.

The parasympathetic division, on the other hand, is responsible for the body's "rest and digest" response. It promotes relaxation, conserves energy, and regulates functions such as digestion and elimination.

Specific Regulation by the Autonomic Nervous System

The autonomic nervous system, particularly the sympathetic division, regulates the activity of various organs and body parts. Here are some examples:

- The autonomic nervous system regulates the activity of internal organs such as the heart, lungs, stomach, and intestines. It controls heart rate, blood pressure, breathing rate, and digestion.

- The autonomic nervous system does not directly regulate the activity of the upper limbs (or "upper extremities"), such as the arms and hands.

- The eyes are regulated by the autonomic nervous system. The sympathetic division dilates the pupils, while the parasympathetic division constricts them.

- The autonomic nervous system does not directly regulate the activity of skeletal muscles. Skeletal muscles are primarily controlled by the somatic nervous system, which is responsible for voluntary movements.

In summary, during active periods, the sympathetic nervous system of the autonomic nervous system is primarily responsible for initiating and maintaining the body's response. The nervous system is interconnected with the musculoskeletal and endocrine systems, and it regulates the activity of internal organs, the eyes, and various bodily functions. The somatic nervous system controls voluntary movements of skeletal muscles.
