Describe The Key Components Of The Central Nervous System

The skeleton is often described as a solid, moveable framework that supports the body. Bone is a strong and rigid form of connective tissue. It also works as levers and anchor plates to allow movement to take place. Bones also work for alternative body systems for example the blood cells develop in their fatty inner tissue (red marrow). The body draws from mineral stores in bones during crucial times of shortage, for instance when calcium is needed for healthy nerve functioning. The skeletons key components are ligaments, the axial skeleton; this consists of the skull, spine, ribs, and breast bone. The appendicular skeleton which consists of limb bones, shoulders and hips.

Muscular Muscles work with the skeleton, which provides a range of pulling forces, powerful to intricate, for movement. Involuntary muscles work automatically in order to control internal processes, such as blood distribution and digestion. Muscles particularly rely on nerves to control them and blood to supply them with oxygen and energy. The key components are skeletal muscles which are attached to bones, smooth muscle within organs, tendons and cardiac muscle of the heart.
Nervous

The nervous system comprises of three components. The central nervous system (CNS) is fundamental to the human body’s structure. It is
The two oval shaped testes are placed outside of the body in a pouch of skin called the scrotum, where they can maintain the optimum temperature for sperm production which is estimated at three degrees which is lower than body temperature. Testes are oval shaped glands which are responsible for the manufacture of sperm the sex hormone testosterone. From each testis, sperm is passed through a bent tube called the epididymis for the last stages of maturation. They are stored in the epididymides until they are broken down and reabsorbed or
