Organization of Muscle Tissue Laszlo Vass‚ Ed.D. Version 42-0016-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions‚ diagrams if needed‚ and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Purpose:
Premium Muscle Acetylcholine Nerve
is activated by the rise in blood temperature and is responsible for for controlling the mechanisms that will decrease the blood temperature. Efferent nerve impulses are sent from the hypothalamus to multiple different corrective mechanisms to try to decrease the blood temperature and maintain it at approximately 37℃. The efferent nerve impulses causes the smooth muscles to relax and as a result‚ opens up blood capillaries near the surface of the skin. This is known as vasodilation as the blood

communication systems in the brain The Nervous System and the Endocrine System Nervous System: extensive network of nerve cells that carry messages in pulses of electrical and chemical energy throughout the body. This is the network that first comes to your rescue by accelerating you heart and tensing your muscles for action. Endocrine System: a slower acting communication network that sends a follow up message that supports and sustains that support the emergency response initiated by the nervous system

is threatening. It then signals to our body how to react. Studies hall all revealed that before anger affects any part of our body‚ it has to affect our brain first. The brain is our internal alarm system. It signals to the rest of our body when we are happy‚ sad‚ angry‚ in pain‚ etc. this alarm system within our brain triggers the release of adrenaline which causes us to heighten our awareness and responsiveness. This causes glucose to gush through our blood stream and muscles giving us the ability

biologist named Otto Loewi‚ who would later win the Nobel Prize for his work. Acetylcholine has many functions: It is responsible for much of the stimulation of muscles‚ including the muscles of the gastro-intestinal system. It is also found in sensory neurons and in the autonomic nervous system‚ and has a part in scheduling REM (dream) sleep. The plant poisons curare and hemlock cause paralysis by blocking the acetylcholine receptor sites of muscle cells. The well-known poison botulin works by preventing
Premium Nervous system Dopamine Neurotransmitter
Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are
Premium Neuron Action potential Neurotransmitter
neurotransmitter when it binds to the GABAA receptor. Subsequently‚ this leads to greater influx of chloride ions into the nerve cell‚ lowering the electrical potential of the cell and therefore having an overall inhibitory effect on the central nervous system‚ leading to anxiolysis‚ amnesia and sedation (Rang et al. 2011). In addition to benzodiazepines‚ opioids can be administered to enhance sedation and relief pain. With respect to the case study‚ benzodiazepines might have minor side effects on
