Chapter 41, Problem 10TYU
Summary Introduction
To describe: The fact that acetylcholine has an excitatory effect on skeletal system but an inhibitory effect on cardiac system by the help of a hypothesis.
Introduction: Neural transmission takes place by an efficient system which is nervous system. The information is taken up by the neurons that transmit the information to the brain for interpretation and then responds. The information is described in the form of stimuli that is detected by neural receptors.

33.
Acetylcholine (Ach) is the neurotransmitter at the neuro-muscular junction. The
motor neuron releases Ach which diffuses across the synaptic cleft and binds to Ach-
receptors (called nicotinic-receptors) on the post-synaptic muscle cell. Ach-
receptor-blockers keep the Ach from binding to the nicotinic-receptors and
therefore, block the action potential from occurring in the muscle-cell. This is the
mode of inhibiting and paralyzing the skeletal muscles during surgery. Why might
this be useful and necessary?
a. without the Ach-receptor blocker the spinal-reflexes would cause the body to
respond to the surgeons' knife.
b. the ACh-receptor blocker is used to disable the motor cortex
c. the ACh-receptor blocker completely inhibits the sympatheticand
parasympathetic nervous systems, allowing the medical team to control all
fundamental physiologic systems.
d. the Ach-receptor blocker is used to disable the sensory cortex.

Often, the action potentials occur so rapidly that watching a screen to see them occur is not helpful. A speaker is powered by the signals recorded from a neuron and it pops each time the neuron fires an action potential. These action potentials are firing so fast that it sounds like static on the radio. Electrophysiologists can recognize the patterns within that static to understand what is happening. Why is the leech model used for measuring the electrical activity of neurons instead of using humans?arrow_forward
