Question
Chapter 13.3, Problem 3CC
Summary Introduction
To determine: The diagrammatic representation of map of the stretch reflex using standard steps of a reflex pathway.
Introduction: Reflex actions are generated involuntarily in the body against stimuli. Information about such actions is processed, and accordingly the response action is done by the body in very short time. Reflex actions are generally seen in situations involving negative feedback.

In the knee jerk, contraction of quadriceps is accompanied by relaxation of
the opposing flexor muscles. The contraction of quadriceps is mediated by a
monosynaptic reflex (as stated above), and the relaxation of the
antagonists is due to a dual connection reflex.
The relaxation of antagonists is mediated by an inhibitory transmitter
released by interneurones - these are called the la inhibitory interneurones,
How do we name a dual connection reflex?
monosynaptic
disynaptic
tricynaptic

The Baroreceptor reflex illustrates very well the principles and elements of a negative feedback loop.1) What is the typical circumstance in which the baroreceptor reflex is stimulated? What is the stimulus for the reflex and the response?2a) Using the terms for a homeostatic negative feedback loop or a reflex, describe both the function AND anatomical elements serving that function for each of the following as it applies to the baroreceptor reflex known as: an effector.
2b) applied to the baroreceptor reflex known as: the integration center?
In a combination of excitatory or inhibitory synaptic connections the following is true
it is poorly exemplified by the stretch reflex during a knee jerk
in the stretch reflex circuit the biceps or flexor muscle gets activated
in the stretch reflex circuit the quadriceps or extensor muscle gets activated
an inhibitory interneuron inhibits the flexor motor neuron
an inhibitory interneuron inhibits the extensor motor neuron motor neuron

- A nerve conduction velocity test measures nerve conduction velocity. In this test, an electrical stimulus is applied to a peripheral nerve and the length of time it takes for the corresponding muscle to contract is measured. Because the length of the nerve from stimulus point to muscle and the time it takes for the muscle to contract are both known, NCV can be calculated. This test result is helpful in distinguishing between different types of pathologies. For example, a patient with muscle weakness is being tested by a physician. There are three possible sources of the weakness: Disease of the muscle itself such as muscular dystrophy. In this condition, normal muscle tissue is replaced by adipose tissue and the muscle becomes incapable of contraction. Disease at the neuromuscular junction (NMJ) such as myasthenia gravis. This condition is described in the Skeletal Muscle Histology exercise and results from damage to the acetylcholine receptors on the muscle end plate.
