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

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

commissures. Different groups of arthropods exhibit different degrees of fusion of the ganglia. In insects the first ganglion‚ the subesophageal‚ is formed by fusion of three pairs of ganglia; it sends nerves to the mouthparts and to the salivary glands. The segmental ganglia in the thorax and abdomen provide nerves to the appendages‚ dorsal muscles‚ sense organs‚ and heart. Insects have 3 pairs of thoracic ganglia and up to 10 abdominal ganglia. The most common sensory receptors in arthropods are

Human Physiology/Senses ← The Nervous System — Human Physiology — The Muscular System → Senses Are the physiological methods of perception. The senses and their operation‚ classification‚ and theory are overlapping topics studied by a variety of fields. Sense is a faculty by which outside stimuli are perceived. What are Senses? We experience reality through our senses. A sense is a faculty by which outside stimuli are perceived. Many neurologists disagree about how many senses

1.An extensive network of specialized cells that carry information to and from all parts of the body is called the nervous system. 2.The basic cell that makes up the nervous system and which receives and sends messages within that system is called a neuron. 3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon. 4.On a neuron‚ the branch-like structures that receive messages from other neurons are the dendrites. 5. The cell body of the neuron‚ responsible
