What else can I help you with?
What reflex prevents a muscle from exerting too much tension?
It's called the stretch reflex and involves muscle spindles which are sensorimotor organs located in skeletal muscle.
Reflex that control skeletal muscle are called?
Somatic Reflex
When a muscle is suddenly stretched what is called to action?
Stretch Reflex
Stimulation of the patellar tendon results in a muscle contractions called what?
A reflex.
How does the stretch reflex cause the quadriceps femoris muscle group to contract?
Tapping on the patellar tendon stretches receptors called the muscle spindles in the quadriceps muscle group of the anterior thigh. This stimulus evokes a rapid motor reflex to contract the quadriceps and shorten the muscles. This process is called the patellar reflex.
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 reflex regulates the activity of smooth muscle?
autonomic reflex
Is a gag reflex a somatic reflex?
No, a somatic reflex are the reflexes of the skeletal muscle movements. The gag reflex is considered to be an autonomic reflex.
What is effector muscle for calcaneal reflex action?
The effector muscle for the calcaneal reflex (also known as the Achilles reflex) is the gastrocnemius muscle in the calf. When the Achilles tendon is tapped, it causes a contraction of the gastrocnemius muscle, resulting in plantar flexion of the foot.
Is the corneal reflex a somatic reflex or an autonomic reflex?
This particular reflex is autonomic as the affected muscle, constrictor pupillae muscle, is a smooth muscle and not under conscious control. Typically if you can consciously contract the muscle, any reflex associated with that muscle is somatic in nature.
The myotatic reflex is provoked by activation of What in a stretched muscle?
The myotatic reflex is provoked by activation of muscle spindles in a stretched muscle. These muscle spindles are sensory receptors that detect changes in muscle length and help regulate muscle contraction and body position. When a muscle is stretched, the muscle spindles send signals to the spinal cord, leading to a reflex contraction to prevent overstretching.
Why does not the patellar reflex happen when your leg is straight?
When the leg is straight, the muscle spindle receptors in the quadriceps muscle are not stretched enough to stimulate a reflex response. The reflex occurs when the muscle is quickly lengthened, activating the sensory receptors in the muscle and sending a signal to the spinal cord to trigger a reflexive contraction of the quadriceps muscle.
