Cerebral hemisphere

What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. It gathers information about and reacts to internal and external stimulus. Don’t Shoot the Messenger Much of the CNS is made up of neurons. Each neuron has a cell body, which includes a soma with a nucleus, a nucleolus, a cytoplasm called the perikaryon, and wide branching extensions called dendrites. Dendrites are like antennae which receive signals from other neurons or body cells.…

System first. The Central Nervous System consists of the brain and the spinal cord. The Cerebral Cortex, which is involved in a variety of higher cognitive, emotional, sensory, and motor functions is more developed in humans than any other animal. It is what we see when we picture a human brain, the gray matter with a multitude of folds covering the cerebrum. The brain is divided into two symmetrical hemispheres: left (language, the ‘rational’ half of the brain, associated with analytical…

Sexual orientation is one of the largest sex differences in humans. While the vast majority of the population is heterosexual, there is a small portion of people that are bisexual and heterosexual, who are attracted to the same sex. According to Freberg (2015), sexual orientation is “a stable pattern of attraction to members of a particular sex (p.344).” In this research paper, I will briefly discuss the biological contributions to sexual orientation. We will first discuss the contributions of…

In my opinion, the human body is one of the most complex mechanisms known to mankind – even more complex than the latest iPhone X. The human body comprises of many different systems: the digestive system, the endocrine system, the exocrine system, the muscular system, the urinary system, the reproductive system, the respiratory system, the circulatory system, the sympathetic system, the skeletal system. The human body consists of about 300 bones at birth and this number decreases to 206 by…

Witelson find about Einstein’s brain? Which part of the brain was unusually larger than the normal brain? Sandra Witelson discovered the Einstein’s peripheral lobe as 15 percent larger than the average brain. 3. What are gyri in the brain? The human cerebral cortex is very deeply wrinkled, and the…

was a teacher for 10 years. He had an arteriovenous malformation (AVM) that he had surgery on. During the surgery, complications caused a hemorrhagic stroke in the left middle cerebral artery. The middle cerebral artery delivers fresh blood to the brain, this incident caused damage to the language areas of the left hemisphere. These complications have also led to hemiparesis on the right side of his body, mainly in his right arm, and impaired language abilities. His Speech Language Pathologist…

Important Vocabulary (highlighted in the handout): Stimulus, neurons, dendrites, neurotransmitters, axon, myelin, action potential, graded potential, transmembrane potential, neuroglia, cerebrum, spinal cord What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. This system only makes up about 3% of a human’s body weight but serves a vital function, gathering information about and reacting to its environment and any stimulus. Don’t Shoot the…

Have you ever thought about the complex process your brain goes through just to eat a slice of pizza? Most people will never know how complex consuming a slice of pizza is. Various parts of the brain are used from just thinking about feeling hungry and ordering the pizza, to after it has been consumed and the digestive process occurs. One must use many parts of their brain to accomplish all of these simple tasks. While I was sitting down, working on my Psychology homework for Professor Bacon,…

Henry M. grew up just outside of Hartford, Connecticut and was known as a young man with an above average intelligence. Some of his favorite activities were ice-skating, listening to detective shows on the radio, and he enjoyed figuring out what would happen in the detective shows before it was released.

Alzheimer’s is a common form of dementia that leads to memory loss that affects our intellectual abilities. Huntington’s disease on the other hand is a brain disorder caused by a defective gene in our chromosome. If I had a choice between the two diseases I would choose Alzheimer’s and here is my rationale for choosing this disease.…
