knee jerk
The patellar tendon, just underneath the kneecap
This reflex involves the cervical spinal nerves
The patellar ligament initiates the knee jerk reflex when tapped. When the patellar tendon is tapped just below the patella, the sensory neurons detect the sudden stretch and send an impulse to the spinal cord. This reflex causes the contraction of the quadriceps muscles, resulting in the extension of the leg.

Reflex
A knee-jerk reaction is an instinctive reflex. For example, if someone begins screaming insults at you for no apparent reason, your automatic reaction (knee-jerk) may be to get angry and scream insults right back at them, instead of first trying to find out why they are angry at you.
yes, the knee relfex felt when tapped just below the knee cap on the patellar tendon is a somatic reflex which is a contraction of skeletal muscles. the opposite would be autonomic relfexes which consist of contractions of smooth or cardiac muscle or secretion by glands.
