MUSCLE RECEPTORS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sensors that provide information about joint angle, muscle length and tension
A
Proprioceptors
B
Mechanoreceptors
C
Exteroceptors
D
None of the above
Explanation: 

Detailed explanation-1: -Muscle spindles are proprioceptors that consist of intrafusal muscle fibers enclosed in a sheath (spindle). They run parallel to the extrafusal muscle fibers and act as receptors that provide information on muscle length and the rate of change in muscle length.

Detailed explanation-2: -Proprioception relies on mechanoreceptors located in deep tissues such as muscles and tendons. However, low-threshold mechanoreceptors located in the skin and hair follicles may also contribute to proprioception, in addition to touch.
