single letter difference in their DNA sequences. From this they were able to focus on two genes whose variants seem to be linked to sexual orientation. One of the genes is located on chromosome 13, which is active in a part of the brain called the diencephalon which contains the hypothalamus. Another gene was discovered on chromosome 14 and is mainly active in the thyroid, but also the brain. This gene is called TSHR, it makes a type of protein that clings on to a hormone that stimulates the thyroid

tube will eventually close and bend and then “the superior end goes on to form the major components of the brain” (Rouse, 2016). The component that will form first is the “prosencephalon or the forebrain” (Rouse, 2016) then this develops into the “diencephalon or thalamic structures and telencephalon or cerebral hemispheres” (Rouse, 2016). During this phase, “cleavage of the prosencephalon will occur resulting in two cerebral hemispheres, a left one and a right one” (Rouse, 2016). Formation of the midline

temporal lobe occipital lobe, cerebellum, and medulla oblongata. They all play in major components of the forebrain, midbrain, and hindbrain. The forebrain consists of the telencephalon and diencephalon. In the telencephalon consists of the cerebral cortex, basal ganglia, and limbic system. The diencephalon consists of the thalamus and hypothalamus. The next component of the brain is the midbrain also known as the mesencephalon. The mesencephalon is composed of the tectum and tegmentum. The last

A. Which of the four major areas of the brain (cerebrum, diencephalon, cerebellum and brain stem) was obviously much larger in the human brain in the diagram than in the sheep brain? Why do these structures differ so dramatically? 13. B. What is the significance in the size difference in the olfactory bulbs between

Gestation is one of the most fascinating processes the human body can perform. Starting from the combining of a sperm and an egg, in 44 short weeks, a baby is formed. There are many instances in which fetal development may go wrong but fortunately, there are also many mechanisms to prevent harmful agents from hurting the child. The first trimester is when a majority of the major organs are formed. In the third month of pregnancy, the fetus already has a working nervous system, an immature muscular

Traumatic Brain Injury and Post Concussive Syndrome Neurological Degeneration Dementia produces physical changes in the brain and some areas shrink and other widen. Dementia is a term used to describe symptoms of mental or communication impairment found in a variety of brain conditions including Alzheimer’s disease (AD). In approximately 20% of the cases dementia can be reversed with the other 80% being irreversible. Dementia is generally marked by memory loss, forgetting appointments, forgetting

How the Scientific Revolution changed the way people viewed the universe During the Middle Ages, various people had questions about the Earth. For many centuries, society believed that the Earth was the center of the universe and that planets, the moon, and the sun rotated around it. This is known as the geocentric theory. The church believes in the geocentric model. In the Renaissance, intellectuals throughout Europe discovered new theories about the universe. These intellectuals had created a movement

Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system, a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

Research indicates that cases of Alzheimer’s disease involve “…damage to improper function of on or more of these brain areas…: the prefrontal lobes, the hippocampus, amygdala, and diencephalon (van der Flier et al., 2005; Caine et al., 2001). Researchers have also identified biochemical changes that occur n cells as memories form; studies suggest that acetylcholine and glutamate are in low supply or at lease function differently, in

The diagnosis and the nature of two physiological disorders In this assignment, I will be writing about two physiological disorders; a stroke which is a circulatory disorder and asthma which is a respiratory system disorder. A physiological disorder is “an illness that interferes with the way that the functions of the body are carried out.” (Billingham et al, 2016). Stroke A stroke is the first physiological disorder I will be writing about. A stroke is a circulatory disorder which affects the brain
