For my project‚ I chose tetanus because when I was eleven‚ I got my tetanus shot. At the time‚ I didn’t know what tetanus was so my dad explained it to me. I thought the topic was interesting. At the time‚ I thought that tetanus was only caused by rust getting on an open wound or cutting yourself with something rusty. I only knew that it stiffened your face muscles and could kill you. When I saw tetanus on the list on Edmodo‚ I just knew I had to learn more about it. I am so glad that I chose it

The nervous system is one of the smallest yet one of the‚ if not the most‚ complex systems in the human body. It can be broken down into two main subdivisions‚ the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system contains about 85 billion neurons and includes the spinal cord and brain. It is considered the control center of the body and processes all types of incoming sensory information. The peripheral nervous system is composed of all the other tissue

men vs women.txt A male brain is about 10% larger than the female brain and has 5% more brain cells. That sounds like good news for men but the female brain more than makes up for its disparity in size in other ways.But women have more nerve cells in certain areas. Women also tend to have a larger corpus collusum — the group of nerve fibers that connects left and right hemispheres. That makes women faster at transferring data between the computational‚ verbal left half and the intuitive‚ visual right

The nervous system is an important part of the human body. The system is made up of many different parts and each part is placed in either the central or peripheral nervous systems. These two parts work together and bring physical feelings and the proper reaction to them. The peripheral nervous system is the larger of the two systems. The peripheral nervous system consists of two more systems inside of it. The two other systems are the somatic and autonomic nervous systems. The somatic nervous system

The tectospinal tract connects the midbrain and the spinal cord. It is responsible for motor impulses that arise from one side of the midbrain to muscles on the opposite side of the body. The function of the tectospinal tract is to mediate reflex postural movements of the head in response to visual and auditory stimuli. Damage signs would show prevention in being able to coordinate the head‚ neck‚ and eye movements. Sensory receptors perform countless functions in our bodies including mediating vision

The Effects of Temperature on the Extracellular Firing Rate of Action Potentials in the Ventral Nerve Cord of the Periplaneta Americana Andrew Goldsmith (andrew.goldsmith@uconn.edu)‚ Tuesdays 1-4PM Section: 2 (Partner: Ana Charalambides) Abstract In polikiotherms it is known that the amount of locomotion varies based on the environmental temperature. We believe that this is caused by differences in the neural activity. We therefore investigated how temperature changes affect the extracellular

3. Why don’t the terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface becomes less positive. Additionally‚ when depolarization reaches a certain threshold‚ an action potential is initiated

Inside our brain‚ there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor
