Pregunta 8
Pregunta
In the myotatic reflex, is the sensory input from the muscle spindle excitatory to the motor neuron in the spinal cord or inhibitory? Why?
Respuesta
-
Excitatory - this leads to contraction of the muscle which prevents damage that may be caused by stretch of the muscle when excess strain is placed on it.
-
Inhibitory - this leads to absence of excitatory contractory signals and therefore the muscle relaxes. This helps to prevent damage to the muscle.

Pregunta

- True
- False
