Adrenal cortex

You can feel a rush of energy go through your body. Your hands start to shake, you are alert, the energy you have is through the roof. It’s called adrenaline. The hormone secreted by the adrenal glands, especially in conditions of stress, that gives you that extreme rush of energy that makes you feel like you can do almost anything. Most of the cases, when you get an adrenaline rush, are in fight or flight situations. The fight-or-flight response is a physiological reaction that occurs in…

part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which develop from the forebrain. The hemispheres have the cerebral cortex which contains ten billion nerve cells. Underneath is the brainstem, and behind that is where the cerebellum is. The outermost layer of the cerebrum is the cerebral cortex is divided…

have Posttraumatic stress disorder are in denial. PTSD can reduce the use of the amygdala due to the deep brain stimulation (Langevin et.al., 2016).The deep brain stimulation can inadequate the control of a cerebral target from the medial prefrontal cortex (Langevin et.al., 2016). Posttraumatic stress disorder is more common to be found in women than men (Bangasser, Wiersielis, & Khantsis, 2016). People who have Posttraumatic stress disorder have flashbacks and not always in their right state of…

I froze in horror as I read the Facebook message that was sent to me. He’s gone. My heart fell to my gut. I felt a sharp pain down my spine. My head started throbbing- I wanted to throw up. My body trembled, and my hands turned to ice. I started looking around the room to make sure I wasn’t dreaming. I was trying to wake myself up from a nightmare that was my reality. According to Sapolsky, a neuroscientist of great renown, a “Stressor” is an event in the outside world that knocks you out of…

of fats into glucose. Whereas undergoing acute stress, starts with the sympathetic nervous system. Here the hypothalamus shoots nerve impulses into the spinal cord, which then travels to the preganglionic sympathetic nerve fibers, and finally the adrenal medulla which promotes catecholamines such as epinephrine. One might experience a rise in blood pressure and heart rate, relaxation of the bladder, and glucose to enter into the…

Adrenoleukodystrophy (ALD) is a condition which affects the ability of adrenal glands to produce adrenaline and myelin, which insulates the nerves in the brain and spinal cord. This diminishes the ability of the brain to communicate effectively with the rest of the nerves. This condition was initially identified in the early 1900s and was originally called Schilder-Addison disease (2). The cause of this condition originates in the peroxisomes, which are tiny structures in the cell which assist…

adolescents, but the failure of this response to subside over time may be indicative of anxiety (Casey 20). Structural MRI studies of adolescents with anxiety disorders have shown structural anomalies in the superior temporal gyrus, the ventral prefrontal cortex and the amygdala (Paus…

Fear is by far the most driving force behind the evolution of humanity and of all other species. Fear is the single strongest force behind humanity and its survival because fear is what stops people from doing something that could harm or kill them. Fear is the most powerful chemical reaction in the brain, requiring more chemicals and less time to register then thoughts or memories and lasting much longer. Fear affects everyone in some way, and some much more cripplingly then others. Fear has…

medicine for the paycheck, prestige, or simply to carry on the family business, my desire for pursuing a career in medicine has been driven by another motive entirely. The odds were one out of 15,000 and I was chosen — I was diagnosed with Congenital Adrenal Hyperplasia (CAH) at the age of eight. CAH is a genetic disorder that affects the general health, growth, and development of the body. Not only does this condition involve the taking of daily medication for the rest of my life, I am also…

MEDICAL RECORD NUMBER [Number] [Name] is an almost 25-year-old girl who has a diagnosis of congenital adrenal hyperplasia, which is definitely a very severe form.

She was diagnosed with a disorder in the newborn period and did undergo genital surgery, with removal of her clitoris and establishment of a normal external female genitalia. She has been highly noncompliant in taking her medications and…
