The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will

show the difference in heart rates before and during intense exercise. Aim: The aim of the investigation was to discover how the heart rate varied with the intensity of exercise. The heart rate is a term describing the regularity of the cardiac cycle. The heart rate is the amount of times it contracts (beats) in a unit of time‚ nearly always per minute. At rest the adult female’s heart rate regulates 75 bpm (beats per minute) but this varies between people. If the heart rate is measured before‚ during

THE NERVOUS AND THE ENDOCRINE SYSTEM. Humans need both the Nervous and the Endocrine systems basically because they do different things in different ways. They both have a co-ordination role and send instructions to other parts of the body. The nervous system does this by way of neurotransmitters‚( chemical messengers)‚ which are able to get messages through at very high speeds‚ and the endocrine system by way of hormones‚( also chemical messengers)‚ which are released from glands and travel

Assignment 3 Written Essay Questions 1. a) We are able to experience different types of sensations because our nervous system encodes messages. German physiologist Johannes Muller in his doctrine of specific nerve energies described a kind of code which is anatomical. In his doctrine‚ Muller explains that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways that lead to different areas of the brain. For example‚ when the ear

is the Nervous System? The nervous system is an organ system that is a network of nerves and fibers that nerve impulses between different parts of the body‚ and is responsible for sending‚ receiving and processing. All the organs and functions rely upon these nerve impulses to function. It’s an example of the body’s master control unit. The nervous system is the control and communication system of your body. its job is to send and receive messages to your body. the nervous system controls

The perineurium is a sheath of special‚ fiber-like cells that ties the axons of each fascicle together. Epineurium is the connective tissue that surrounds the entire nerve trunk and gives off vascular connective tissue septa that traverse the nerve and separate fascicles from one another. | | Single myelinated axon | Normal nerve | Axons thicker than one micron in the CNS and peripheral nervous system (PNS) are myelinated. Myelin is a spiral sheet of cell membrane wrapped around the axon. In

The Central Nervous System is composed of the brain and the spinal cord and one of it’s primary functions is to send out messsages to the rest of the body. One chronic illness that affects the Central Nervous System is Multiple Sclerosis. Roughly 2 million people througout the world have been faced with this disease‚ and “in the United States‚ it is estimated that 450‚000 people are affected‚ with 10‚000 new cases per year” (Goodman & Fuller 772). This disabiling condition has been found more prevelant

The Nervous System and Aging Sensory changes can influence the way we see‚ hear‚ taste‚ smell‚ and respond to touch and pain. This in turn affects how we experience the world and react to things. A significant sensory change can rob us of many simple pleasures and complicate the tasks of daily living. It may mean reduced mobility‚ increased dependence on others‚ inaccurate perception of the environment‚ reduced ability to communicate and socialize‚ or loss of self-esteem. Sensory changes vary

The job of the central nervous system is to process and send information to the peripheral nervous system. The nervous system consists of the brain‚ spinal cord and a complex network of neurons. The central nervous system is responsible for receiving‚ sending and interpreting information from the whole body. The nervous system also monitors and coordinates internal organ functions and responds to external changes as they occur. The two main organs of the central nervous system are the brain and spinal
