  • The central nervous system CNS is the combination of the brain and spinal cord. the Function of the nervous system has two main sub parts the somatic which is voluntary and the autonomic which is involuntary. The autonomic nervous system maintains certain body processes like,  blood pressure and the rate of breathing, that work you thinking about it. The somatic system is made up of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin.
  • The peripheral nervous system (PNS) is the combination of nerves outside the CNS.

Cranial nerves start at the brain from and also stops in the brain, while spinal nerves at the the top of the spine and end at the bottom of the spinal cord.

    The second, nerves of the PNS are sensory afferent neurons which transmit impulses from skin and other sensory organs and from different places within the body to the CNS.
    Motor efferent neurons transmit impulses from the CNS to effectors for example muscles or glands.

    Third is the somatic nervous system SNS which tells the contraction of skeletal muscles when to move. The autonomic nervous system ANS controls the actions of glands, organs, and many involuntary muscles, for example cardiac and smooth muscles.

    The parasympathetic nervous system activates tranquiler mechanism, such as starting the secretion of saliva or digestive enzymes into the stomach and small intestine

    both sympathetic and parasympathetic systems target the same organs, but normally  work in opposite of each other. For example, the sympathetic system increases the heartbeat, on the other hand  parasympathetic system slows the heartbeat. they both systems activate when it is best to maintaining homeostasis.

The nervous system can make three types of muscle tissue contraction. For example, skeletal muscle contracts to move the skeleton, cardiac muscle is swayed because of heart rate increasing  during exercise, and also smooth muscle contracts in the  digestive system as moves food  through the digestive tract. Responses also includes the control of glands in the body as well, such as the production and secretion of sweat by the sweat glands in the skin to lower body temperature.

    Hypothalamus
    The hypothalamus is found in the lower central part of the brain. It is important in regulation of metabolism and body temperature. It also secretes hormones that stimulate or suppress the release of hormones in the pituitary gland.
    Pituitary Gland
    The pituitary gland is found at the base of the brain below the hypothalamus. It is the most important part of the endocrine system because it makes hormones that control many of other endocrine glands.
    Thyroid Gland
    The thyroid gland is found in the lower front part of the neck. It makes thyroid hormones that regulate the body's metabolism. The pituitary gland regulate the release of thyroid hormones in to the body . Thyroid hormones also help control normal blood pressure, heart rate, digestion, and reproductive functions.
    Adrenal Glands
    The two adrenal glands are found on top of each kidney. The adrenal glands makes  hormones called corticosteroids, which controls  the body's metabolism and the balance of salt and water in the body.

An example of this is when a mother is breast feeding. the baby sucks the nipple of its mother and the sensory cells in the nipple send out signals to the hypothalamus, which in turn hypothalamus then responds by releasing the hormones from the pituitary gland. The hormones is released directly into the bloodstream where it moves to its target cell, which is a mammary  gland when talking about breast. The mammary gland then responds to the signals from the hormone by releasing milk through the nipple, feeding the child

The endocrine system affects almost every organ and cell in the body. but the hormones go around the body, each type of hormone is crated to work for certain organs and tissues. The endocrine system gets some help from organs such as the kidney, liver, heart and gonads, which have secondary endocrine functions. The kidney, for example, secretes hormones such as erythropoietin and renin.
