into the subarachnoid space (p.461) 3. Where is the primary defect in Parkinsons disease and Huntingtons? The inferior-most portion of the basal ganglia is the substantia nigra‚ which synthesizes dopamine‚ a neurotransmitter and precursor of norepinephrine. Its dysfunction is associated with Parkinsons disease (p.455) The basal ganglia system is believed to exert a fine-tunning effect on motor movements. Parkinsons disease and Huntingtons diseare are conditions associate with defects of the basal

ENDOCRINE SYSTEM The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones‚ chemical messengers. The endocrine system is composed of glands that release their hormones directly into the bloodstream for chemical signaling of target cells. Endocrine glands do not have a duct system and are called ductless glands. These glands release hormones directly into the blood or lymph. These glands include the pituitary gland‚ the pineal gland

the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones in conjunction with stress through the synthesis of corticosteroids and catecholamines‚ including cortisol and adrenaline (epinephrine)‚ respectively. Anatomy and function Anatomically‚ the adrenal glands are located in the retroperitoneum situated atop the kidneys‚ one on each side. They are surrounded by an adipose capsule and renal fascia. In humans‚ the adrenal glands are

In one of the chapters Matt Ridley concludes that chromosome 10 is related to stress. He relates chromosome 10 to stress by a small organic molecule called cholesterol that correlates to stress levels. The cholesterol gets manufactured in the body from sugars in the diet. This small organic molecule called cholesterol can form many steroids that have important functions in the body like‚ testosterone‚ cortisol‚ progesterone‚ aldosterone and oestradiol. Matt Ridley focuses on cortisol which causes

Body’s Response to Acute Exercise Musculoskeletal response: There is an increase in blood supply as your body is working "overtime”. The blood supply has to increase because it has to go to the parts in your body which you are exercising the most e.g. If you are taking a run‚ the blood supply will increase because your legs will need more energy‚ therefore there will be more blood circulating your legs than normal because you are overworking them. Your muscles and all your body organs need
