How are the nervous tissue protected?
The brain is covered by three protective layers called meninges. The space between the meninges is filled with a fluid called cerebrospinal fluid. This fluid protects the brain against shocks and mechanical injuries. This fluid also maintains a constant pressure in and around the brain.
How does the nervous tissue cause Action Class 10 notes?
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 do nervous tissue maintains muscular movement?
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.
Do nerves run through muscles?
At the neuromuscular junction (where nerves connect to muscles), the impulse crosses from the motor nerve to receptors on the motor end plate of the muscle, where the impulse stimulates the muscle to move.
What organ controls muscle movement and senses?
The nervous system controls various organs of the body directly. The brain also receives information from many organs of the body and adjusts signals to these organs to maintain proper functioning. The skeletal system makes up the framework of the body and allows us to move when our muscles contract.
What organ controls all body functions?
The human brain is the body’s control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage and general perception of the world. The human heart is a responsible for pumping blood throughout our body.
Which organ controls all activities of your body?
The nervous system is the control center of the human body. It is made up of the brain, spinal cord, and nerves. It receives and interprets stimuli and transmits impulses to organs. Your brain uses the information it receives to coordinate all of your actions and reactions.
What part of your nervous system does the logical thinking?
Cerebrum. The largest part of the brain is divided into two halves called hemispheres. The left one, which controls the right side of your body, handles speech for most people. It also controls logic, math calculations, and pulling facts from your memory.
What is the main problem that your central nervous system will try to solve?
a. What is the main problem that your central nervous system will try to solve? Probably to try to escape out of this problem and not die in there Our nervous system will try to remember a past experience like this and will try to find a response and escape from all those enemies.
