Biological Bases of Behavior Nervous System Made up of neurons‚ which are the nerve cells. These send electrical impulses to one another ( through a process known as firing) telling the body what to do. The parts of a neuron include: Cell Body (a.k.a. soma) – Main part of neuron; contains basic cell parts such as nucleus‚ ER‚ etc.; also has dendrites extending from it. Dendrites – bushy fibers which extend from the soma; receives impulses and directs them towards soma Axon – an extension

the heart‚ air cells of the lung and certain tubules of the kidney. Filtration or diffusion occurs rapidly across this thin epithelial sheet. Cuboiodal and columnar cells line glands and the digestive tract and are involved in secretion‚ absorption. Pseudo stratified columnar tissue lines there respiratory tract. Its glands secret mucus‚ and the cilia stroke the pollutant-laden mucus to the pharynx. Stratified squamous epithelium lines the skin‚ oral cavity‚ much of the pharynx‚ oesophagus‚ vagina

One of the assumptions of the Cognitive Approach is that internal mental processing should be studied. This is different to the Behaviourist Approach as they believe in behaviour that is observable but cognitive psychologists study the mind internally. Another assumption of the Cognitive Approach is that the human mind should be compared to a computer to see how it works. Cognitive psychologists believe humans input information (senses)‚ process it (memory‚ perception etc.) and output it (behaviour)

known as toxic diffuse goiter‚ is the most common cause (80%) of hyperthyroidism in the United States (Rakel & Bope‚ 2008). Hyperthyroidism is a hypermetabolic disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs (Nettina‚ 2006). Over activity of the thyroid gland leads to high levels of thyroid hormones in the bloodstream and speeding up of vital body functions (Grave ’s Disease‚ 2008). Graves’ disease is an autoimmune disorder‚ meaning the body’s immune system

Cortisol is produced by the adrenal glands. The adrenal glands are part of our endocrine system and produce hormones that regulate our organs‚ tissues‚ and glands throughout the body. When cortisol levels are low the hypothalamus‚ a gland located in the lower portion of the brain‚ produces corticotropin releasing hormone (CRH). This stimulates the pituitary gland to produce adrenocorticotropin hormone (ACTH)‚ which then stimulates the adrenal glands to produce and release cortisol‚ when

Hypothyroidism The endocrine system is a series of glands within the body. These gland impact a lot of our body including calcium levels and what we find joy in ( the pituitary gland releases dopamine if we enjoy something). Because there are so many glands in our bodies‚ there are a lot of things that can go wrong. Two of the things that could go wrong are Hyperthyroidism (overactive Thyroid) and Hypothyroidism (underactive Thyroid). While they are both malfunctions of the Thyroid gland‚ Hyperthyroidism
