Reaction Experiment On Reaction Time Experiment

Although unlike the change in concentration, when the temperature of the reactants were either increased or decreased their was no significant change. As shown in table 4. When the temperature was either increased or decreased to 10°C, 30°C, 40°C and 50°C the average times are all within one second of each other. Except for when the reactants were cooled to a further 5°C the reaction time was increased by more than double the reaction time. This showing that the results from the investigation did not fully support the stated hypothesis.

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

The components of the nervous system that are involved in the physical sensation is the peripheral nervous system, which is divided into two groups they are, sensory and motor divisions. The sensory impulse moves through the body by stimulating a receptor in the skin, and it goes through the sensory neurons and also travels through the afferent fibers, the spinal cord and also into the brain.

Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.

In the organization of the Human Nervous System it is divided into sections such as the sensory system, which gathers and process information from the surrounding environment: motor systems which responds from environment by sending signals and information to facilitate movement behavioral responses and the associational system which is a meditator from most multifaceted and least problematic brain functions. Within these different functions of the nervous system it is divided into two components where these functions can happen the central nervous system that comprises of brain and spinal cord and peripheral nervous system that embodies nerves and ganglia.

Continuing on we as a class learned about the spinal cord, which is a column of nerves lining our back, as well as the central nervous system, which is the human body’s main processing unit. Chapter two focuses primarily on these two aspects of the body. The central nervous system is the brain and spinal cord, the brain, hindbrain, and midbrain are in charge of the senses. Hearing and sight for example are dealt with in the forebrain. The nervous system includes many different working pieces that control the body. Such as Dendrites; these are the hairs on the neurons. Ions have both negative and positive neurons which each has three, included with the soma in the cell body. Axon is the long tube of it, and the terminal button is the end of the tube.

Our focus for this week’s lab was the vertebrate nervous system. The nervous system is composed of two divisions called the central nervous system and the peripheral nervous system. Within these two divisions there are three types of neurons that allow us to recognize changes in our environment and help us to respond accordingly. The three neurons that are found are called sensory neurons, interneurons, and motor neurons.

Solutions can be made to have delayed reactions. Delayed reactions are interesting to watch but can they might be able to speed up the process of their reactions. Delayed reactions can be speeded up to have a quicker reaction than the normal reaction/control group. The control group takes about 15 seconds for the chemicals to react. The 1st chemical is clear/optical and has no smell which will be referred to as

There are two types of nervous system cells, they receive and send electrochemical responses to the body. Neuron cells are the conducting cells of the nervous system. Neurons have a cell body with dendrites branching from the main body, an axon which is the long tail that extends from the main body that is wrapped in myelin to create a protective sheath around the axon that also helps speed the neurotransmissions. The glial cell is the supporting cells of the

Neurons are what make up the nervous system. The nervous system is very complex for all the activities that this system performs. It main function is to communicate. It sends nerve impulses to the muscles (effectors), the muscles receive stimuli and tuned electromechanical signals that are sent to the

In this lab, the team concluded that being distracted with an activity that diverts optical attention away from the focal point, such as texting, significantly increases reaction time. The other distractors, including listening to music and talking on a cell phone, had effectively no impact on reaction time in comparison to having no distraction.

The organs of the nervous system can be divided into two groups. One group consisting of the brain and spinal cord, forms the central nervous system. The other, composed of the nerves ( bundles and axons) that connect the central nervous system to other body parts, is called the peripheral nervous system. Together, these systems provide three general function: sensory, integrative, and motor. The sensory function of the nervous system derives from sensory receptors at the ends of peripheral neurons. These receptors gather information by detecting changes inside and outside the body. Sensory receptors monitor external environmental factors, such as light and sound intensities, and conditions of the body’s internal environment, such as

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 purpose of this paper is to describe and present the replication of The Stroop effect experiment and its effects on Reaction Time (RT). Students (N-49) were given The Numbered Stroop Experiment to measure both the congruent condition and incongruent condition after completing a demographic survey. Two trials are given: both in verbal counting and out loud number recall. RT was measured with stopwatch and was distinctively slower between the two trials. We predicted that reaction time will vary from each subject, moreover RT will be slower when compared to the congruent condition. In our findings indeed, RT was significantly longer, which is consistent with the research of The Stroop Effect (Windes,
