Well, reflexes are functions of the nervous system, which coordinates our actions. The nervous system is the network of neurons that transmits the action potentials. The sensor and neurons are outside the spinal cord, in what is called the peripheral nervous system (PNS).
Which nervous system is reflex?
In addition to regulating the voluntary movements of the body, the somatic nervous system is also responsible for a specific type of involuntary muscle responses known as reflexes, controlled by a neural pathway known as the reflex arc.
What is part of the peripheral nervous system?
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
What parts of the nervous system are involved in a reflex?
The anatomical pathway of a reflex is called the reflex arc. It consists of an afferent (or sensory) nerve, usually one or more interneurons within the central nervous system, and an efferent (motor, secretory, or secreto-motor) nerve. Most reflexes have several synapses in the reflex arc.
Which of the following is an example of reflex?
For example, if you put your hand on a hot stove, a reflex causes you to immediately remove your hand before a “Hey, this is hot!” message even gets to your brain. Other protective reflexes are blinking when something flies toward your eyes or raising your arm if a ball is thrown your way.
Where are the reflexes in your body?
Many reflexes start at the muscle or skin and go to the spinal cord. When the action potential reaches the nerve ending, the signal is transferred to another neuron, such as an interneuron or motor neuron. The action potential then travels outside the spinal cord to a muscle.
What are the 3 parts of the peripheral nervous system?
The Peripheral Nervous System (PNS)
- Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
- Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.
Which is not part of the peripheral nervous system?
brain is NOT a part of the peripheral nervous system. The brain, brain stem and spinal cord are all components of the central nervous system…
What are the two parts of peripheral nervous system?
The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
What are the 4 types of reflexes?
In our discussion we will examine four major reflexes that are integrated within the spinal cord: the stretch reflex, the Golgi tendon reflex, the withdrawal reflex and the crossed extensor reflex.
What are the 5 parts of a reflex arc?
The reflex arc consists of 5 components:
- sensory receptor.
- sensory neuron.
- integration center.
- motor neuron.
- effector target.
Which of these is not a reflex response?
A reflex action is done by neural pathway of reflex arc. In this, the action is done before the impulse reaches the brain. Out of the given options, sweating is not a reflex action. Salivation is a reflex action in which smell of food activate neural pathway and activates muscles and glands.
What are the three reflexes?
- Moro reflex.
- Sucking reflex (sucks when area around mouth is touched)
- Startle reflex (pulling arms and legs in after hearing loud noise)
- Step reflex (stepping motions when sole of foot touches hard surface)
What are the three types of reflexes?
There are three common somatic reflexes discussed in most anatomy and physiology courses.
- Stretch (knee-jerk, patellar) reflex.
- Withdrawal (flexor) reflex.
- Crossed-extensor reflex.
Which of the following describes a reflex?
Description. A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus. … The path taken by the nerve impulses in a reflex is called a reflex arc. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.
