- 4. 4 Learning Objectives 2/28/2021 1st year-Physiology Lab By the end of the practical students should be able to: Identify Radial, Carotid, and brachial pulses in a subject. Record Radial pulse in resting state and after physical exercise. Describe division of nervous system. Describe origin, types and functions of the autonomic nervous system. List differences between sympathetic and parasympathetic nervous system.
- 5. 28/02/2021 Practical Outline • Compositionof Nervous system • Differences between sympathetic and parasympathetic nervous system. • Regulatory effects of autonomic nervous system. • Procedure of radial pulse recording. 5
- 6. Nervous system regulatesbody activities rapidly through nerve impulses (action potentials). Nervous system is divided into two main parts: A. Central Nervous System (CNS) Brain and spinal cord. B. Peripheral Nervous System (PNS) Composed of all nerves coming out or into the CNS. These include spinal and cranial nerves. (Somatic & autonomic nervous system) 28/02/2021 6 Introduction

ANS Division Autonomic nervous system Involuntary Inputfrom internal receptor Output to heart, smooth muscles & glands Sympathetic Motor system ‘Fight or flight’ responses Neurotransmitter : noradrenaline ‘Adrenergic System’ Parasympathetic Motor System Relaxing response Neuroransmitter : acytylcholine ‘Cholinergic System’ 28/02/2021 9

- 14. Procedure The subject shouldbe in a resting state (physically and mentally) before recording the pulse. Make the subject to lie down/sit down comfortably at the examination table/chair for some time. Place fingertips (ring, middle and index finger) over the radial artery in the ventrolateral region near the subject's wrist joint. Feel and count the number of pulses for 30Sec. and note them down by multiplying with 2 to convert it into the number of heart beats per minute. 28/02/2021 14
- 15. Repeat thepulse counting twice and note down the reading in pulses per min. Calculate the average of these three values and note down in the table. Repeat the whole above procedure after proper physical exercise. For exercise purposes, run and take three to five rounds in the lab corridor or if treadmill is available do exercise at least 2-3 minutes. Measure the radial pulse and record your observation in the given table. Note the time of the radial pulse come to the normal resting state after exercise. 28/02/2021 15 Procedure
