Describe the gross structure and main functions of all major body systems (P5) Reproductive systems Male (Harvard-wm.org, 2014) The male reproductive system is made up of the scrotum, testes, epididymis, spermatic cords, vas deferens, seminal vesicles, ejaculatory duct, urethra, prostate, cowper glands, the penis and the semen. The scrotum is a sac like structure in which the testes are located, it is found in the pubic region and its job is to regulate the temperature of sperm by

ready to rise to a challenge. And the nervous system quickly returns to its normal state, standing by to respond again when needed. But stress doesn't always happen in response to things that are immediate or that are over quickly. Ongoing or long-term events, like coping with a divorce or moving to a new neighborhood or school, can cause stress, too. Long-term stressful situations can produce a lasting, low-level stress that's hard on people. The nervous system senses continued pressure and may remain

how he inherited behaviour is advantageous because of the useful function it serves. The Human Body * A complex organism made up of many systems. * Acts as a coordinated controlled unit. * It is the function of the Nervous and the Endocrine Systems to act as the coordinator of this controlled unit. The Nervous System and The Endocrine System * Both control and coordinate body activities. * Work separately and in different ways but are liked by the pituitary gland (the master

tissues in the nervous system;the causes are unknown. The cells in the Nervous System that help transmit nerve impulses that control voluntary muscle movements are called Motor Neurons. These Motor Neurons spontaneously degenerate which means that the connections from the brain to the muscles are lost . Without the pathways for the nerve impulses to travel down the muscles, the brain loses control of the voluntary muscles. Sufferers of ALS have virtually lost the

often prescribed by doctors to treat a wide range of conditions, including obesity, depression, and sleeping disorders and are often abused because of the “rush” they bring on. Stimulants act by increasing activity in the central nervous system and the peripheral nervous system. They increase alertness, physical endurance and the ability to stay awake. Heart rate and blood pressure are also increased by stimulants. TYPES OF STIMULANTS Stimulants can be categorized as: 1. Amphetamines 2. Methamphetamines

not interconnected with other neurons die increasing the efficiency of the nervous system. In other words, if the baby’s experiences do not stimulate nerve connections the unused neurons are eliminated by synaptic pruning. The pruning down of the unnecessary neurons allow for the established neurons to build elaborated communication with other networks. This is contrary to other aspects of growth because the nervous system continues more effectively through the loss of

disease Glial cells (also known as neuroglia, or simply glia) are small non-neuronal cells that have numerous functions to maintain a healthy brain. When Rudolf Virchow founded glial cells in 1856, glia was thought to be the glue, which held the nervous system together. (Kalat, 2013) This is not the case. In fact, glial cells are essential to support brain function. “Morphofunctional changes resulting from the plasticity of all the glial cell types parallel the plastic neuronal changes that optimize
