Summary Introduction
Introduction:
The elongation of a tendon and the muscle attached to patellar tendon is known as stretch reflexes. When sharp tap is applied on the patellar tendon, then this type response in known as the patellar reflex.

Select the best answer or answers from the choices given: A reflex that causes reciprocal activation of the antagonist muscle is the (a) crossed-extensor, (b) flexor, (c) tendon, (d) muscle stretch.
a) Describe the processes involved in the knee-jerk reflex and explainwhy it is called a ‘monosynaptic’ reflex.b) While crawling across the floor a child accidentally places her righthand onto a piece of broken glass. How will the flexor muscles of herleft arm respond? What happens to the rest of her body?
Relative to muscles of the back, we have more dexterity and precision in the control of our fingers. This is explained by:
A) The fact that muscles of the back are under autonomic control
B) The smaller ratio of muscle fibers controlled by neurons in the fingers
C) The fact that finger muscles are smaller
D) The smaller threshold potential of finger muscles
