Introduction: The endocrine system is the second greatest control system of the body and has many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In this experiment‚ the effects of TSH and thyoxine on metabolic rate

The endocrine system is the collection of glands that produce hormones that regulate metabolism‚ growth and development‚ tissue function‚ sexual function‚ reproduction‚ sleep‚ and mood‚ among other things. The endocrine system is a very important system in the human body. There are many endocrine glands in this system‚ including -but not limited to- the pituitary gland‚ hypothalamus‚ pineal gland‚ thyroid gland‚ parathyroid glands‚ adrenal glands‚ pancreas‚ gonads‚ placenta‚ thymus‚ heart and gastric

Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues
