How does the nervous tissue cause Action class 10th?

How does the nervous tissue cause action? ANS. When a nerve impulse reaches the muscle,the muscle fibre must move by changing their shape. this is possible as muscle cells have special proteins that change both their shape and arrangement in the cell in response to nervous electrical impulses.

How does a nervous tissue cause action?

When a nerve impulse reaches the muscle the muscle fibre must move. Muscle cells have special proteins that change both their shape and their arrangement in the cell in response to nervous electrical impulses. …

How do muscle cells cause Action Class 10?

The neuron that innervates muscles and transmits the signals to the muscle fibre for initiating the muscle contraction is called the motor neuron. Complete answer: Muscle cells move in response to nerve impulses. This is with the help of a motor unit.

How does nervous tissue maintains muscular movement class 10?

General Science

The nervous tissues maintain the muscle movement. They have point called axons which transfer the brains message to the relative muscle and carry out the action. The brain send the message through the tendons and axons to the the point in action. This whole process is maintained by the nervous system.

How does the nervous tissue cause action Brainly?

It is specialised to react to stimuli and to conduct impulses to various organs in the body which bring about a response to the stimulus. Nervous tissue is composed of neurons, which transmit impulses, and the neuroglia, which assist propagation of the nerve impulse as well as provide nutrients to the neuron.

Which nerves cause the movement of muscles?

Skeletal muscles are attached to bones and produce movement at the joints. They are innervated by efferent motor nerves and sometimes by efferent sympathetic and parasympathetic nerves. Every movement of the body has to be correct for force, speed, and position.

How does muscle tissue respond to nervous impulses?

(I) Acetycholine is released when the neural signal reaches the motor end plate. (II) Muscle contraction is initiated by a signal sent by CNS via a sensory neuron. (III) During muscle contraction, isotropic band gets elongated. (IV) Repeated activation of the muscles can lead to lactic acid accumulation.

How does the action due to nervous tissue in animals is different from response to stimulus in plant?

Explanation: The action due to nervous tissue in animals is different from response to stimulus in these ways. In nervous tissues, action is carried out by the transmission of Electical impulses but in plants in takes place by changing the concentration of water.

What happens in reflex action?

Reflex arcs

Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. … Motor neuron sends electrical impulses to an effector. Effector produces a response (muscle contracts to move hand away).

Which tissue helps in movement along with nervous tissue?

Muscular Tissue

This is a tissue that helps in the movement of the various body parts. They are generally attached to the bones, and thus help in movement.

What is reflex action how it differs from normal function of the brain?

The brain doesn’t have a significant response to it. It differs from the normal functions of the brain as brain need some time to react to anything but reflex are so fast they do not even think. The automatic response of the body to a stimulus is called a reflex action. The response comes out within seconds.

What synapse means?

synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector).

What are the difference between nervous and hormonal mechanism for control and coordination in animals?

The nervous system receives the information, processes it, and triggers reactions. The neurons help in transmitting signals. On the contrary, hormones diffuse through the plasma membrane of the target cells and bind a receptor protein in the cytoplasm of the cell.
