Is an ankle jerk reflex somatic or autonomic?
Ankle jerk is somatic. It is the reflex action, in which the afferent. connecting and the efferent neurons are involved. Autonomic nerves do not supply the striated muscles.
What is ankle jerk?
The ankle jerk, also known as the Achilles reflex, is a deep tendon reflex that occurs when the Achilles tendon is tapped, usually at the back of the ankle. This action causes the calf muscles to contract and the foot to jerk downward. It is often tested during neurological examinations to assess the integrity of the S1 and S2 spinal nerves. A diminished or absent ankle jerk can indicate potential neurological or muscular issues.
Where is the lesion that present with weakness of lower limbs with absent knee jerk and exaggerated ankle jerk?
L3 l4
Which nerve is important for the ankle jerk reflex?
medial popliteal nerve
What is a muscle head?
What i have hear was a that a muscle head is someone who is full of them self and is a big jerk to any one
What is a reflect muscle?
It is a muscle reflex. A very fast, involuntary muscle contraction. Because of this, it causes you to jerk your hand away after touching a hot iron.
Why knee jerk and Achilles reflexes are important for walking?
Knee jerk and Achilles reflexes are crucial for maintaining balance and stability while walking. The knee jerk reflex helps stabilize the leg and maintain posture by automatically adjusting muscle tension in response to changes in the body's position. Similarly, the Achilles reflex aids in controlling the ankle's movements, ensuring a smooth and coordinated gait. Together, these reflexes enable quick adjustments, preventing falls and facilitating efficient locomotion.
What is an example of a stretch reflex triggered by passive muscle movement?
knee jerk reflex
What is the stimulus for the knee jerk flex?
The stimulus for the knee jerk reflex, also known as the patellar reflex, is the stretching of the patellar tendon when the knee is tapped just below the kneecap. This stretch activates sensory neurons that send signals to the spinal cord. In response, motor neurons are triggered, causing the quadriceps muscle to contract and resulting in the quick extension of the lower leg. This reflex helps maintain posture and balance.
What type of neuron's involved in a knee jerk?
sensory neurones motor neurones
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal reflex?
The knee-jerk reflex is a type of stretch reflex, which is a type of spinal reflex. It involves the stimulation of sensory neurons in the muscle spindles of the quadriceps muscle, leading to a quick contraction of the muscle in response to a sudden stretch.
What are the cause of ankle clonus?
clonus is an abnormal response of tendon jerk that occurs only when the center of the reflex is highly facilitated as in UMNL. It is either ankle or patellar clonus . -ankle clonus: if a sudden stretch is applied on tendocalcaneus by dorsiflexion of the foot, there will be a regular oscillation of contractions and relaxations as long as this stretch is maintained
