What fine-tuned sensory receptors detect differences in tension generated by active muscle rather than muscle length
Anastaziya [24]

golgi tendon organs fine-tuned sensory receptors detect differences in tension generated by active muscle rather than muscle length.

  • Gamma motor neurons fire to regain sensitivity, causing the spindle to contract, becoming taut and regaining the ability to transmit muscle length.
  • There are two groups of motor neurons. Extrafusal fibers, the rapidly contracting fibers that give the muscle its power, are innervated by alpha motor neurons.

What is golgi tendon organs?

  • The Golgi tendon organ, which is located close to the point where a tendon joins a muscle, is a sensory ending that resembles a tree and is encased in a spindle-shaped connective tissue capsule.
  • In a male, one tendon organ is attached to 10 to 20 muscle fibers.
  • An endpoint of a typical tendon organ in limb muscles is roughly 0.5 mm long.

Select all that apply. Choose the cells that are diploid. egg nerve bone sperm muscle
Natali5045456 [20]
The diploid cells in this case include nerve cell, bone cell and muscle cell. A diploid cell is a cell that contains two sets of chromosomes, which is double the haploid chromosome number. They include all the somatic cells with exception of germ line cells. Gametes are haploid cells meaning they only have one set of chromosomes. During sexual reproduction, gametes (sperm and egg cells) fuse at fertilization to form a diploid zygote which develops into a diploid organism.
