Anterior pituitary

splits into the anterior cerebral artery and the middle cerebral artery. The anterior cerebral artery supplies blood to the medial surface of the frontal and parietal lobes as well as the corpus callosum. The middle cerebral artery supplies the lateral portions of the hemispheres and has branches that supply internal structures, like the basal ganglia and internal capsule. Before the anterior and middle cerebral arteries split, the blood branches out to supply structures, such as pituitary…

Triiodothyronine, with a chemical name of 3,3',5-Triiodothyronine (T3), is one of four thyroid hormones that exhibit biological activity, and contains 3 iodines and 2 tyrosine’s, as seen in Fig. 1. 20 % of T3 is formed from the amino acid tyrosine within specific follicle cells of the thyroid gland by the oxidative condensation of its biological precursors, monoiodotyrosine and diiodotyrosine, and is then subsequently secreted into the bloodstream. The remaining 80% is produced from the…

I Blame the Hormones By: Taylor Aubin Organs and tissues that make up the endocrine system are the hypothalamus, pituitary gland, thyroid gland, thymus, suprarenal glands, pineal gland, parathyroid glands, heart, kidneys, adipose tissue, digestive tract, pancreas, and gonads. The effects of the endocrine system are vast and impact almost every organ and cell of the body. This system produces hormones that help maintain homeostasis through the regulation of metabolism, growth, tissue function,…

feeling such as pain, stress, and emotional experiences. (1) 2 Pituitary gland – the “master endocrine gland” because it secretes many hormones that control other endocrine glands. It is a “pea-shaped structure that attaches to the hypothalamus by a stalk. The pituitary gland contains an anterior lobe called the anterior pituitary that function to secrete hormones that regulate bodily activities from growth to reproduction. 3. anterior pituitary gland – secrete hormones that…

system in the body. It is an essential hormone that stimulates the body growth, normal brain function and secreted by the somatotropin cells in the anterior pituitary gland. There is a condition of abnormal body grow such as pituitary gigantism and pituitary dwarfism which the body over create grow hormone or doesn’t create enough GH. Another name for pituitary dwarfism is growth hormone deficiency. According to the Children’s Health study, the estimate between one in 14,000 and one in 27,000…

Studies conducted by Stephen Walter Ranson demonstrated that a specific population of nuclei identified as the supraoptic nuclei of the hypothalamus had nerve projections that terminated in the posterior pituitary, and through animal studies, lesioning this tract of nerve fibers without failure produced DI (Fisher et al., 1938; Ranson 1937). A significant breakthrough came about through discovery of control and regulation of ADH release through experimental…

iodine can be obtained in the diet, this is no longer a cause for the disease. The main known causes for hypothyroidism is an autoimmune disease known as Hashimoto’s Thyroiditis, faulty treatments that have been given to “cure” hyperthyroidism, and pituitary failure which leads to the failure of TSH. While unfortunately there is no cure for the disease, the main known medication to help regulate the thyroid gland is known as Levothyroxine (Warren et al.,…

exposure to unhealthy surrounding. A person grows, but there are cases where growing exceeds the normal rate and reaches to extreme compare to other people. This occurrence is called acromegaly, in which the secretion of growth hormone (GH) in the pituitary gland exceeds its normal production even after the growth plates in the body has closed already. Thus, making structures and bones that are still responsive to growth hormone particularly in the hands, feet and face to overgrow (Marieb,…

Task One Explain the functions of the following The Temporal Lobe The temporal lobe is placed in the base of the cortex behind the temples. It is one of the four exceeding lobes in the cerebral cortex. The temporal lobe develops sensory information. It controls select listening and the data collected from the ears. Sound and speech is also created here. The temporal lobe conceives significant speech, including sounds and pitches. Long term and visual memories are stored here. The temporal…

The pituitary gland produces several important hormones that control body functions such as growth, development, reproduction, and metabolism. One of these hormones is growth Hormone (GH). In childhood, GH is important for proper development and growth. In adults GH maintains healthy bone and muscle function. If there is not enough growth hormone, a child will not grow to his potential stature. If there is too much growth hormone a child will grow excessively tall. If there is an excess of…
