Background Smooth muscle is one of three muscle fiber types found in animals. Unlike skeletal and cardiac muscle cells‚ smooth muscle cells are not striated‚ and have single nuclei. Smooth muscles are typically under control of the autonomic nervous system‚ and do not contract voluntarily. Smooth muscle contracts slowly‚ and does not exhibit the characteristic “twitch” seen in skeletal muscle. In addition‚ smooth muscle is not prone to muscle fatigue‚ making it an ideal component of sphincter muscles

and glands throughout the body produce hormones. As generations progress‚ new psychological and behavioral traits are earned and learned. This paper will explain hormones and the endocrine system‚ glands associated with the endocrine system‚ behavior genetics‚ and evolutionary psychology. The endocrine system is the system of the body in which releases hormones into the bloodstream. The hormones then cause different reactions within the body‚ and these reactions shape part of human behavior. There

Renal system The renal system consists of two kidneys‚ two ureters which come out of the kindeys and a single bladder which collects the urine before it goes into the urethra. It also involves the sphincter muscle which is located just below the bladder and its purpose is to control the flow of urine. The kidneys have renal veins which take the blood from the kidneys into the main vein in the body which is known as the vena cava‚ they also have short renal arteries which come out of the main vein

gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine residues in thyroglobulin molecules‚ inside the follicle cell. (www.vivo.colostate.edu/hbooks/pathphys/endocrine/thyroid/chem.html) This hormone regulates growth and controls the rate of chemical reactions in the body.

found in animals‚ plants‚ and microbes. In humans‚ melatonin is produced by the pineal gland‚ a small endocrine gland located in the center of the brain but outside the blood–brain barrier‚ Production of melatonin by the pineal gland is inhibited by light to the retina and permitted by darkness. Its onset each evening is called the dim-light melatonin onset . The melatonin signal forms part of the system that regulates the sleep–wake cycle by chemically causing drowsiness and lowering the body temperature

stimulation by releasing hormones from the hypothalamus; called the master endocrine gland; releases 6 hormone products which all function via second messenger systems. Four of the six are hormones that regulate the functioning of other endocrine glands: thyroid stimulating hormone (TSH)‚ adrenocorticotropic hormone (ACTH)‚ follicle stimulating hormone (FSH)‚ and luteinizing hormone (LH) Remaining two affect non-endocrine targets: growth hormone(GH) and prolactin.

It consists of two sections‚ called lobes; these lobes are about the size of half of a large plum. The lobes are located on the left and right side of the trachea‚ connected by a small piece of tissue‚ known as the isthmus‚ which runs across the trachea.
