Adrenal cortex

Congenital adrenal hyperplasia is the overdevelopment of the adrenal glands from birth. In a healthy person, cortisol is used to decrease the release of adrenocorticotropic hormone. ACTH is used by the pituitary gland which stimulates the adrenal gland. However, people with CAH have a genetic limitation where they are unable to produce correct amounts of cortisol. Without cortisol to exert a negative feedback on ACTH, it continues to be secreted causing the adrenal gland to secrete larger…

known as adrenalin in the form of epinephrine from the postganglionic axons into the blood stream. The epinephrine is distributed into the circulatory system where it is distributed throughout the body. The epinephrine will travel to different places of the body and have different responses where ever it goes. Also epinephrine does not go into the cells of the body it only binds to the surface of cells by attaching to protein of cells. When it reaches the liver it binds to proteins and then…

Introduction Adrenaline refers to a natural stimulant created in the medulla in the adrenal organs. And also partly by certain parts of the central nervous system's neurons. In a few minutes time amid a distressing circumstance, adrenaline is immediately discharged into the blood, sending impulses through the autonomous nervous system to organs to make a particular reaction, for instance the production of sweat and saliva, pupil dilation and heart rate. It is responsible for the human…

activity B) by increasing renal excretion of Ca2+ C) by decreasing renal excretion of HPO42D) by decreasing renal production of calcitriol E) All of these are correct. ____ 70. The adrenal glands A) lie superior and medial to the kidneys. B) have an inner medulla derived from embryonic ectoderm. C) have an outer cortex that secretes hormones critical to maintenance of homeostasis. D) A and B are correct. E) A, B and C are…

Non-classical adrenal hyperplasia or NCAH is a disorder that affects both men and women from late childhood through the rest of their lives. Compared to its sister form, classical congenital adrenal hyperplasia, it is non-life threatening. The Mayo Clinic, a service that gives people medical information and helps set up doctor appointments, defines NCAH as “a collection of genetic conditions that limit your adrenal glands' ability to make certain vital hormones.” These vital hormones include,…

You’re hiking through the woods when all of a sudden you hear a stick crack. You look cautiously around for the hazard, but you see no one. Your heart starts racing. You begin to sweat. Your mouth dries and you feel butterflies in your stomach. Your hair stands on end. You feel a surge of energy and in a split second you find yourself running away from the noise. Whether you’re aware of it or not, your body just went through a response known as the fight or flight response also known as the…

The main three sections of the brain are the hindbrain, the limbic system, and the cerebral cortex. The hindbrain consists of the medulla which is directly above the spinal cord and controls breathing, heartbeat, and other vital life functions like the things we don’t have conscious control over. It also has pons which are in the uppermost level…

1 Hypothalamus – a small region of the brain that is a major link between the nervous and endocrine system. The hypothalamus controls the autonomic nervous system and regulates body temperature, hunger, thirst, fear, rage, and sexual behavior. The hypothalamus control 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…

simple things like breathing. The brain is supplied with oxygen to keep it alive by a network of blood vessels. Structure of the brain The brain is made up of 4 main parts and they are: ● The cerebral cortex, ● Limbic system, ● The cerebellum ● and the brain stem The cerebral cortex The cerebral cortex is split into two cerebral hemispheres (the left and right hemispheres). Sometimes…
