Describe a reflex arc using a suitable diagram?
A reflex arc is a neural pathway that controls a reflex action. It consists of a sensory neuron carrying the sensory input to the spinal cord, an interneuron within the spinal cord that processes the information, and a motor neuron that transmits the response to the effectors (muscles or glands). This allows for a rapid and automatic response to a stimulus without conscious thought.
What are the two types of effectors and how does each respond to stimuli?
There are two main types of effectors namely homotropic and heterotropic effectors. Homotropic effectors substrate themselves while the heterotropic effectors produce enzymes to help in various processes in the body.
How does effector relate to reflex arc?
An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.
What skeletal muscle cells are the effectors of the withdrawal reflex?
The skeletal muscle cells that are the effectors of the withdrawal reflex are the muscles that move the limb away from the painful stimulus. These muscles receive signals from the central nervous system to contract and move the limb as part of the reflex response to protect the body from harm.
What is the sacral reflex arc?
The sacral reflex arc refers to the neural pathway that controls involuntary responses in the sacral region of the spinal cord. It involves sensory neurons detecting stimuli and transmitting signals to the spinal cord, which then sends motor signals back to the muscles or glands in that region to produce a reflex action. This reflex arc helps regulate functions such as bowel and bladder control.
What are the effectors of a reflex arc?
Muscles and glands are the possible effectors of a reflex arc
What are the effectors of the salivary reflex?
The effectors of the salivary reflex are the salivary glands, which produce and release saliva in response to stimuli such as the sight, smell, or taste of food. The parasympathetic nervous system is primarily responsible for stimulating the salivary glands during this reflex.
Last step of a reflex arc?
PNS delivers motor response from CNS to effectors...
Which of these is not one of the essential compponents of a reflex arc?
The brain is not one of the essential components of a reflex arc. Reflex arcs involve sensory receptors, afferent neurons, interneurons, efferent neurons, and effectors, but they do not involve the brain in the reflex loop.

In the reflex arc a muscle or gland is considered to be the?
In the reflex arc, a muscle or gland is considered to be the effector. Its role is to respond to the stimulus provided by the sensory neuron and produce the appropriate action, such as muscle contraction or gland secretion.
What muscles in the limbs are the effectors of a withdrawal reflex?
Flexor Muscles
What are effectors of the nervous system?
The effectors of the nervous system are muscles and glands. They respond to nervous stimuli.
What muscles of the limbs are effectors of withdrawal reflex?
flexor muscle
What are the two types of effectors in the body?
Muscles and Glands.
How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.
What is the pathway of reflex?
reflex arc
