what is an example of the somatic nervous system？
The primary function of the somatic nervous system is to connect the central nervous system to the body's muscles to control voluntary movements and reflex arcs. For example, imagine that you are out for a jog in the park one brisk winter morning. As you run, you spot a patch of slick ice on the path ahead.2021年4月14日
Beside above,What is an example of somatic?
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. Germ cells have half the number of chromosomes that somatic cells have.
Considering this,What is an example of the somatic nervous system at work?
One common example is the knee reflex: hitting the patellar tendon just below the knee cap with a reflex hammer leads to an automatic contraction of the quadriceps – which results in the lower leg kicking out.
Keeping this in consideration,What are the types of somatic nervous system?
The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves . It is also responsible for the reflex arc, which involves the use of interneurons to perform reflexive actions. Besides these, there are thousands of other association nerves in the body.
Correspondingly,What does the somatic nervous system?
The somatic nervous system (SNS), or voluntary nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles.
EXAMPLES. Physiological changes induced by the sympathetic nervous system include accelerating the heart rate, widening bronchial passages, decreasing motility of the large intestine, dilating the pupils, and causing perspiration.
Examples: Knee jerk reflex and withdrawal reflex. Involve muscle groups and related joints, bones, tendons, ligaments and fascia; and are referred to as inter-joint reflex movements. Examples: Foot grasp reflex and Babinski reflex.
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.
The somatic nervous system (SNS) is part of the peripheral nervous system, and is associated with activities traditionally thought of as conscious or voluntary, such as walking.
Spinal nerves, considered part of the peripheral nervous system, generally refer to mixed spinal nerves, which carry motor, sensory, and autonomic information between the brain and spinal cord and the rest of the body.
The somatic nervous system controls such voluntary actions as walking and smiling through the use of efferent motor nerves, in contrast with the function of the autonomic nervous system, which largely acts independent of conscious control in innervating cardiac muscle and exocrine and endocrine glands.
Functions of the Somatic Nervous System This response determines the location and strength of muscle contraction across different parts of the body. Therefore, the primary function of the somatic nervous system is to connect the CNS with organs and striated muscles in order to enable complex movements and behavior.
