Question
Chapter 14, Problem 19DYKB
Summary Introduction
To explain:
The differences between a stretch and Golgi tendon reflex.
Concept introduction:
Stretch reflex gets activated upon the stretching of muscles. Golgi tendon reflex causes the contraction of muscles and changes in tension. It is composed of sensory nerve endings in a muscle-tendon junction or a tendon.

[C] the muscle will not contract. [D] the number of impulses in spindle la afferents is smaller than when a discharge alone is increased. [E] the number of impulses in spindle la afferents is greater than when a discharge alone is increased.arrow_forwardPut the following events in chronological order. (Some of the steps may be missing.)1) Ca*+ floods into the pre-synaptic neuron.2) ch (Acetylcholine) binds to ACh receptors in the sarcolemma.3) Na+ floods into the post-synaptic muscle cell.4) The A.P arrives at the pre-synaptic terminal causing Ca+ channels to open.5) Ach from the synaptic vesicles spills into the pre-synaptic cleft.6) A post-synaptic action potential results in the muscle fiber (depolarizationarrow_forwardAre all the fibers in a tendon oriented in the same direction?

- Muscle spindles are the sensory receptors that monitor the length of skeletal muscles. When the length of the hamstrings changes between standing and seated positions, which structure is responsible for adjusting the length of the intrafusal muscle fibers of the muscle spindle?

- 1) For each of the following reflexes, detail what the sensor is, the integrator, and the effector. Also note the neuronsinvolved in the reflex (like alpha motor neuron).a. Myotatic (stretch reflex)b. Autogenic Inhibition (Golgi tendon organ reflex)c. Flexor Reflex 2) You stimulate an alpha motor neuron and measure the force of contraction in a control muscle from a mouse. You then add Substance X, a newly synthesized product from your organic chemists. You observe that there is adecreased force of contraction following the same type of motor neuron stimulation.a. Draw your experimental setup and what force you measure before and after administering Substance X.Hint: You’ll need to include something to stimulate the muscle and something to measure the force. Whatyou measure is force upon stimulation (mN, milliNewtons) before and after addition of X.b. Hypothesize one way that Substance X could be inhibiting muscle contraction. Design an experiment…arrow_forwardWhat would happen without input from gamma motor neurons? A) Information about velocity would continue, but information about length would no longer be possible. B) The spindles would be unable to provide feedback as the muscle contracted. C) Neither the intrafusal nor extrafusal fibers would contract. D) The extrafusal fibers would not contract, but the intrafusal fibers would continue to contract.arrow_forwardAn antibody has been isolated that binds to F-actin but not to G-actin.
