What are the 3 major components of a reflex arc?

Reflex Arc Components

• Sensory neurons are the cells that contain sensory receptors.
• Interneurons are like the middleman of the nervous system.
• Motor neurons connect with interneurons in the spinal cord.
• Muscles are what cause us to take action.

What are the components of a reflex arc quizlet?

Suppose that you are interested in determining how far the ball travels.

What are the four components of the reflex arc?

The simplest example of a spinal reflex is the monosynapic reflex arc, having four components:

• A receptor (in this case, the muscle spindle).
• An afferent component (sensory input).
• A central component (spinal processing).
• An efferent component (motor output).

What are the 7 main steps in a reflex arc?

Reflex actions

• Receptor in the skin detects a stimulus (the change in temperature).
• Sensory neurone sends impulses to relay neurone .
• Motor neurone sends impulses to effector.
• Effector produces a response (muscle contracts to move hand away).

What are 5 components of the reflex arc?

The reflex arc consists of 5 components:

• sensory receptor.
• sensory neuron.
• integration center.
• motor neuron.
• effector target.

What is a 3 neuron reflex arc?

There are three main types of neuron: sensory, motor and relay. These different types of neurons work together in a reflex action . A reflex action is an automatic (involuntary) and rapid response to a stimulus, which minimises any damage to the body from potentially harmful conditions, such as touching something hot.

Which specific component of the reflex arc is confined to the CNS quizlet?

Interneurons are multipolar neurons that are confined to the CNS and are linked together in chains that form complex neuronal pathways.

What is an arc reflex?

The reflex arc is a special type of neural circuit that begins with a sensory neuron at a receptor (e.g., a pain receptor in the fingertip) and ends with a motor neuron at an effector (e.g., a skeletal muscle).

What are the 5 reflex arc?

So the reflex arc consists of these five steps in order-sensor, sensory neuron, control center, motor neuron, and muscle. These five parts work as a relay team to take information up from the sensor to the spinal cord or brain and back down to the muscles.

What are the 5 steps of the reflex arc?

Which of components of a general reflex arc are listed in the order?

Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ is the correct order of general reflex arc.
