What is an example of somatic?
Somatic cells are the cells of an organism that are not germ cells, or reproductive cells. Somatic cells are highly specialized and can be very different from one another. Some examples of somatic cells include nerve cells, skin cells, and blood cells.
What are some examples of reflexes?
A few examples of reflex action are:
- When light acts as a stimulus, the pupil of the eye changes in size.
- Sudden jerky withdrawal of hand or leg when pricked by a pin.
- Coughing or sneezing, because of irritants in the nasal passages.
- Knees jerk in response to a blow or someone stamping the leg.
Is the knee jerk reflex somatic or autonomic?
Autonomic Reflexes Activity 1- Patellar reflex The patellar tendon reflex or knee-jerk reflex is a monosynaptic stretch reflex that assesses the nervous tissue between (and including) the L2 and L4 segments. It can be done by tapping the patellar ligament (just below the knee) with a reflex hammer.
Is breathing an example of a somatic reflex?
One-third of all responses coincided with the period of stimulation, i.e., breathing started and ended at or close to the onset and cessation of stimulation. These responses, which we have called “the somatic-respiratory reflex,” are described in this section.
What are some examples of somatic reflexes?
Examples: Rolling over, sitting up, walking and jumping . Somatic reflex examples are included below for innate lifelong reflexes, primary infant motor reflexes, and lifelong reflex schemes .
What are reflexes classified as somatic reflexes?
Reflexes classified as Somatic Reflexes include… (7) abdominal Achilles corneal reflex crossed-extensor reflex gag reflex patellar reflex plantar reflex. The simple stretch reflexes are… Achilles reflex & patellar reflex. The superficial cord reflexes are…
What is the difference between a somatic and autonomic reflex?
The Structure of Reflexes. One difference between a somatic reflex, such as the withdrawal reflex, and a visceral reflex, which is an autonomic reflex, is in the efferent branch. The output of a somatic reflex is the lower motor neuron in the ventral horn of the spinal cord that projects directly to a skeletal muscle to cause its contraction.
Is reflex autonomic or somatic?
There are two types: autonomic reflex arc (affecting inner organs) and somatic reflex arc (affecting muscles). Autonomic reflexes sometimes involve the spinal cord and some somatic reflexes are mediated more by the brain than the spinal cord.
