Background The stress response in the body triggered by the sympathetic nervous system (SNS) contains two different chemicals – neurotransmitters and hormones. Neurotransmitters‚ specifically norepinephrine (NE)‚ are released into the postganglionic synapses of the sympathetic nervous system (SNS) during flight or fight response. NE carries out its effects on a target cell by binding to and activating adrenergic receptors. NE is usually eliminated through the reuptake into presynaptic cells and enzymes

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

1. Explain both the anatomical and functional divisions of the nervous system. Include the subdivisions of each. The nervous system’s function is to monitor stimuli occurring inside and outside the body‚ process and interpret this sensory input‚ and respond by activating effector organs. It consists of the Central Nervous System (brain and spinal cord)‚ and the Peripheral Nervous System (neurons that carry messages to and from the CNS). 2. Describe the composition and function of the cell

The Relationship Between The Nervous System and The Endocrine System The cells and tissues in the body are delicate and easily disrupted. They will only be able to function well if all aspects of their chemical and physical environment is continuously adjusted to keep them stable and in equilibrium. The process in which several body systems work together to maintain the balanced environment is called homeostasis. The endocrine and nervous system work closely together to help maintain homeostasis

conditions could affect one’s heart rate. In the life of a human‚ the heart beats approximately forty-five million times per year varying based off of factors like age‚ gender‚ physical activity level (1). Furthermore‚ throughout the course of a day‚ the heart can vary in its heart rate from a number of different environmental changes such as prolonged standing‚ altered breathing (inhale vs. exhale)‚ and jolts of excitement such as being startled. Relating to the heart rate of an individual is their

glandular tissues. Glandular tissues are generally composed of cuboidal cell or columnar cell. Exocrine glands release substances like sweat and saliva through ducts on to the surface of the body. Exocrine glands include merocrine sweat glands‚ apocrine sweat glands and holocrine glands. Merocrine sweat glands‚ also known as eccrine sweat glands‚ are present through out the body and they release sweat that contains urea‚ electrolytes and many other compounds. Because the sweat contains urea‚ it contributes

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They

What happened to the R-R interval and heart rate after exercise? After exercise the R-R interval increased steadily from 0.48 to 0.68 seconds‚ while the heart rate BPM decreased steadily from 123 to 76; both trending back towards the resting values. What happened to the T-P interval during exercise? Outline what this means for ventricular filling time. During exercise there was a significant drop in the T-P interval which then steadily increased when exercise was completed. The T-P interval represents
