Golgi tendon reflex inverse myotatic is disynaptic

- is the inverse of the stretch reflex.

a. Active muscle contraction stimulates the Golgi tendon organs and group lb afferent fibers.

b. The group lb afferents stimulate inhibitory interneurons in the spinal cord. These interneurons inhibit «-motoneurons and cause relaxation of the muscle that was originally contracted.

c. At the same time, antagonistic muscles are excited.

d. Clasp-knife reflex, an exaggerated form of the Golgi tendon reflex, can occur with disease of the corticospinal tracts (hypertonicity or spasticity).

- For example, if the arm is hypertonic, the increased sensitivity of the muscle spindles in the extensor muscles (triceps) causes resistance to flexion of the arm. Eventually, tension in the triceps increases to the point at which it activates the Golgi tendon reflex, causing the triceps to relax and the arm to flex closed like a jackknife.

Diabetes 2

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
