Which part of the central nervous system controls reflex activities?

The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain. The brain is responsible for integrating most sensory information and coordinating body function, both consciously and unconsciously.

What part of central nervous system controls reflex actions?

Answer: The reflex actions which are rapid responsea or movements to the stimulus are controlled by the SPINAL CORD and not by the brain or muscles.

What part of the nervous system is responsible for reflexes?

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.

Which part of nervous system controls involuntary actions?

The autonomic nervous system regulates involuntary and unconscious actions, such as internal-organ function, breathing, digestion, and heartbeat. This system consists of two complementary parts: the sympathetic and parasympathetic systems.

Are reflexes CNS or PNS?

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 is a function performed by the central nervous system?

The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.

What organs are 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 are the two main physical components of the central nervous system?

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord.

What is reflex action in nervous system?

Nervous system – Reflexes

A reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron.

What is the functional relationship of the peripheral nervous system to the central nervous system?

The peripheral nervous system’s main job is to send information gathered by the body’s sensory receptors to the CNS as quickly as possible. Once the CNS has understood the information, the PNS will relay the specific orders back out the body.

Which part of the brain controls involuntary activities of the body?

The medulla oblongata is the part of the brain which is responsible for controlling all the involuntary actions of the body.

What are 3 reflexes in humans?

Types of human reflexes

  • Biceps reflex (C5, C6)
  • Brachioradialis reflex (C5, C6, C7)
  • Extensor digitorum reflex (C6, C7)
  • Triceps reflex (C6, C7, C8)
  • Patellar reflex or knee-jerk reflex (L2, L3, L4)
  • Ankle jerk reflex (Achilles reflex) (S1, S2)

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.

Who controls reflex?

Reflex actions are those actions takes place along with stimuli. These actions are controlled by the medulla oblongata or the mid brain. These actions are controlled by spinal cord.
