What is Infrapatellar Tendon?
The infrapatellar tendon, also known as the patellar tendon, is located below the kneecap and connects the patella to the shinbone. It plays a key role in enabling extension of the knee joint and is important for activities like running and jumping. Injuries to the infrapatellar tendon can result in conditions like patellar tendonitis.
What is the insertion point of the quadricep?
The insertion point of the quadriceps is the patella, through the patellar tendon, which then attaches to the tibia bone below the knee joint.
What is the patella connected to?
It is connected to the tendon of the quadriceps femoris muscle.
What two structures does the pateller ligament connect?
The patellar ligament connects the patella (kneecap) to the tibial tuberosity, which is a bony prominence on the tibia bone below the knee joint. This ligament is an extension of the quadriceps tendon and plays a crucial role in knee extension and stability.
What is patellar knee-jerk reflex a somatic or autonomic reflex?
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.
What is the effector involved the patellar reflex?
In order to provoke the patellar reflex one must strike the patellar tendon with a tendon hammer (and only a tendon hammer, striking with an ordinary hammer is ill-advised). In other words, strike the region immediately below the patella.

Which ligament of the initiates the knee jerk reflex when tapped?
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.
Where is the patella nerve located?
The saphenous nerve (which will become the patellar nerve) is a purely sensory nerve that crosses below the knee from medial to lateral and innervates the skin below the patella.
What are the bones that lie above and below the patella?
The bone above your patella is called your femur.The bones below your patella are called your tibiaand fibula.
What nerve is tested for patellar reflex?
The Femoral nerve. Wikipedia: Striking the patellar tendon with a tendon hammer just below the patella stretches the quadriceps muscles in the thigh. This stimulates stretch sensory receptors (i.e. muscle spindles) to trigger an afferent impulse in a sensory Ia-nerve fiber of the femoral nerve which synapses (without interneurones) at the level of L4 in the spinal cord, completely independent of higher centres.
What does the patellar reflex employ?
The patellar reflex employs the sensory and motor nerves in the leg that control the contraction of the quadriceps muscle in response to tapping the patellar tendon just below the knee cap.
Where in the body is a bone called the patella?
The patella is also known as the knee cap, right above the tibia and fibula, and right below the femur.
What is an example of a human reflex?
The most well-known human reflex is the knee-jerk (or patella) reflex. This is the one where you use a reflex hammer to hit the tendon just below the kneecap (or patella). The leg jerks out like you're kicking.
