Short Essay On The Nervous System

Brain controls all of the organs in our body and what makes human different from animals is that we have the ability to think and have our own thoughts. Everything is possible in reality and what makes it possible is our knowledge. Richard Wright, who explains the definition of the word cognitive the best by using his memoir the ‘Black Boy’. In his memoir Richard explains his struggles of life as a child, teen and adult. But eventually succeed using his knowledge and experience. In Richard Wright’s Black Boy, Richard’s cognitive need meets and continuous to achieve his dream by unit people together and taught them how to be a good human being through his writing.

There are two points of view of the evolutionary history of the seal, the first view is the eared seals came from a bear like ancestor and the earless seal came from a otter like ancestor due to some similar function of the internal and external organs . The second view is that seals came from the monophyletic group and in a certain point they share a common ancestor. There was an animal called the enaliarctos and it was the last common ancestor of the seals. This animals spent more time on land than in the water than any other pinnipeds. The enaliarctos swim in the water while using both the foreflippers and hind flippers. In modern seals they do not use the foreflippers, they use their tails for steering in the water and the hind flippers

The nervous system is a compound set of specialized cells and nerves that integrate the voluntary and involuntary actions of the body and send signals between different parts of the body.When it comes to structure, the nervous system has two main parts: the peripheral nervous system and the central nervous system. The peripheral nervous system is made up of ganglia and nerves outside the brain and spinal cord. The central nervous system consists of the spinal cord, nerves and brain.

The brain controls everything the body does. The spinal cord carries messages between the body and the brain. Together, they make up the central nervous system (CNS). Some prescription drugs slow down, or depress, the CNS. Others speed up, or stimulate, the CNS. People who abuse CNS stimulants or depressants give control of their bodies to the drug, sometimes with dangerous consequences.

The brainstem is located underneath the limbic system is the brain stem. The midbrain includes the tectum and tegmentum. The brain stem is made up of the midbrain, pons, and medulla. The midbrain is the rostral part of the brain stem. The pons are a part of the metencephalon in the hindbrain. The medulla oblongata is located between the pons and spinal cord. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. The midbrain is involved in functions such as vision, hearing, eye movement, and body movement. The pons are involved in motor control and sensory analysis. For example, information from the ear first enters the brain in the pons. It also has parts that are important for the level of consciousness and for sleep.

The brain is the most complex organ in our body. It serves as the command center of the human nervous system. The brain is composed of different parts and functions that are dependent upon each other. The brain consists of two distinct sides: the right and left cerebral hemispheres. The side of the brain that endures damage will impact the function on the opposite side of the body and impairs mental capabilities. Hence, any injury or damage to the brain can produce impairment on the brain functions. Brain injuries has often led to low psycho-social functioning (Pierson & Noggle, 2010) as well as a variety of emotional and behavioral symptoms (Wozniak, Krach, Ward, Mueller, Muetzel et al., 2007). The most frequent sequelae after severe brain

Medulla oblongata - I would keep this part of the brain because the brainstem controls and regulates heart rate, breathing, and swallowing. These are necessary functions in order to survive. If you damaged or removed the medulla oblongata, it could result in death.

b) The mammalian nervous system is split into two. The central nervous system consists of the brain and the spinal cord, which coordinates and controls the movement and activities of the body and the peripheral nervous system, made up of the somatic and autonomic system, which forms the connections between the organs and the central nervous system.

The limbic system is located along the border between the cerebrum and the diencephalons. The limbic system plays a role in a person’s emotional states and behaviors. It also is important for the creation of short-term memories and improves long-term memories. This system is also important to learning (Cohen, 2013). The limbic system consists of several structures that play a function in memory, learning, and emotional responses. The two main structures are the amygdala and the hippocampus, which are effected from posttraumatic stress disorder.

Zombie bodies are human bodies-- with a catch of course… You see, the normal nervous system activity is deficient and very little motor control is visible. Zombies do not feel pain and they do not seem to suffer from much blood loss or the need for an appetite. As you can tell already, something unusual is occurring neurologically, metabolically, and biologically when the recently deceased become capable of rising from the dead and desire to kill humans by any means necessary. In a more psychological approach, zombies are considered to be imaginary creatures designed to illuminate problems about consciousness and its relation to the physical world. Though zombies are very distinct from us, we’re not so far off from being zombies ourselves.

All the body systems are used while figure skating. First is the circulatory system. Figure skaters use their arms and legs to dance on the ice and do tricks. The circulatory system flows blood, that is filled with oxygen and nutrients, all over her body. It also has white blood cells that can fight disease for the skater. The second system that is vital to figure skating is the respiratory system. This system allows the skater to breath in oxygen into the lungs. The lungs then transfer it to the circulatory system. It also gets rid of carbon dioxide. The third body system used while figure skating is the musculoskeletal system. This system is one of the most important to a figure skater.

My learning strategy for exam one will be to go over the slides that you posted on Canvas and as well as rereading parts of the textbook that I highlighted and took notes on. The main strategy that I will use to study will be to use each of the

Skin Cancer is 75% most death of cancer in the united states. Skin cancer is mostly made by melanoma. This is the worst skin cancer. It is caused by exposure to ultraviolet (UV) radiation from the sun and from tanning lamps and beds. It mostly comes to woman instead of men. You can tell you have melanoma when you see a change in an existing mole you have on you. It can form anywhere on your body, but mostly on your back, legs, arms, and face. ( It's mostly there because of the UV radiation of the sun that hits your skin. It's mostly also grows on the weirdest growth of your skin. Unlikely people less than 20 get melanoma. But that does not mean that they don't get it, it's just very rare. Most likely the people over the age of 60. Melanoma is also a type of tumor. In stage 0 it is a tumor in situ. Then by stage ll, the tumors are huge. At stage II, the tumor attaches to the lymph nodes. If you don’t treat it well it could seriously hurt

Central nervous system: The central nervous system consists of the brain and spinal cord. The brain is responsible for interpreting most sensory information and bodily functions both consciously and unconsciously. The spinal cord is the conduit between the brain and the rest of the body. The peripheral nervous system: The peripheral nervous system consists of

There are many different areas in the brain. But there three main parts; the forebrain, the midbrain, and the hindbrain. These three parts are very important. We use these three parts daily. The human brain is the fattest organ in the body and may consist of at least 60% of
