Nervous System Lab Report

The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.

The nervous system in general is quite a complex and sophisticated system which is responsible for regulating and coordinating the body’s activities. The central nervous system consists of the brain and spinal cord, mainly responsible for gathering information and responds to any changes within environment.

Fibers that leave the cortex to conduct impulses toward other areas are termedefferent fibers, and fibers that approach the cortex from other areas of the nervous system are termed afferent (nerves or pathways). Fibers that go from the motor cortex to the brainstem (for example, the pons) or the spinal

The nervous system is split up into two main organizations, the central nervous system (CNS) and the peripheral nervous system.

The nervous system is a chain of interconnected nerve fibers which is constructed by the central nervous system and Peripheral nervous system. The job of the nervous system is to send messages from the brain and spinal cord to different parts of the body.

Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.

The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and

The nervous system is a multiplexed body system that controls most other body systems directly or indirectly by sending and receiving signals through a complex system of nerves. As a whole, the nervous system can be broken down into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord while the PNS is composed of peripheral nerves that branch off of the spinal cord and continue to branch to reach the most distal points of the limbs. The PNS can be further broken down into the afferent and efferent division. The afferent division deals with information brought to the CNS from the nerve receptors. Furthermore, the afferent division breaks down into somatic sensory receptors whose

The nervous system is responsible for muscle movement. The nervous system consists of central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is constitute of the brain and the spinal cord, and PNS is a network of nerves that runs throughout the body. The brain sends electrical signals to the CNS, and they are disbursed the PNS to produce body movement (Acrobatiq, 2014). Then, these signals travel back from the PNS to CNS to coordinate the next course of action of the body (Acrobatiq, 2014). The motor cortex section in the cerebrum sends messages to the muscles to coordinate accurate movement. Also, its control balance posture during the exercise and movement. The muscles instructed by the impulses from the cerebrum move in the given direction. They relax and contract according to the message relayed by the motor neurons.

In conclusion, this experiment was successful. The purpose of the experiment was to observe the change in heartbeats per minute before and after a physical activity, in this case, ten jumping jacks. As predicted, the data proved that the hypothesis was correct because you can clearly see in the graph that the heart rate after exercise was higher. One point that I noticed from the data was that the ten jumping jacks affected the subjects differently. Subject two’s heart rate after exercise was significantly higher than subject one’s. Subject one’s heart rate increased only slightly; whereas subject two’s heart rate increased significantly. This experiment is a good basis for additional testing involving heart rates and exercise. If this investigation

In the first part of the practical, we will dissect the heart of a sheep and observe its anatomical structure. We will also examine the structure of blood vessels at a microscopic level. My hypothesis is that by examining the anatomy of the cardiovascular system, we will be able to detect differences in both vessels and the chambers of the heart. In the second part of the practical we will examine the electrical activity of the heart. In doing so my aim will be to produce a familiar ECG reading containing a P wave, QRS complex and T wave. Futhermore, we will take blood pressure readings by listening to the korotkoff sounds of the heart using a sphygmomanometer and stethoscope. We hypothesis that the higher the arm position is from the ground, the smaller the blood pressure reading will

The peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates

The central nervous system and the peripheral nervous system work together to collect information from within the body and from the environment outside it. The systems process all the collected information and send instructions to the body; to obtain an appropriate response. Once the data arrives, the brain will sort and file it before sending out any commands on what to do. The central system is the main command center of the body that contains the brain as well as the spinal cord. The peripheral nervous system contains a network of nerves that connect the rest of the body to the central nervous system.

The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.
