Half of the number of the chromosomal numbers of the diploid cell.
Answer:
Brain
Explanation:
A shock is a medical condition which is caused when the body has the less available substrates for the aerobic respiration and shift to anaerobic cellular respiration.The shock takes place in four-stage in which the second stage is the compensatory stage.
During the compensatory stage, the sympathetic nervous system gets activated to shift back the respiration from anaerobic respiration to aerobic respiration.
The sympathetic nervous system releases the epinephrine and nor-epinephrine which acts on the kidney to maintain blood pressure. During this process, the Brain is not affected by the shock condition.
Thus, Brain is correct.
I have no clue, there is nothing else here to support your question.
Answer:
Intervertebral foramen
Explanation:
These structures are found in between pairs of vertebrae and not only do spinal nerves pass through them, the spinal artery, veins, and transforaminal ligaments do too. While the spinal cord passes through the vertebral foramen, the spinal nerves exit and enter the spine through these intervertebral foramen to 'serve' the rest of the body.
1)
To feel an impulse, the receptor must be sent a signal to the brain where it could be interpreted. The signal should be caught by the receptor, send into the spinal cord, then arrives at the brain.
1. Object touch the heel
2. impulses generated in the receptor cells
3. impulses transmitted through a sensory neuron
4. impulses transmitted through neurons in the spinal cord
5. impulses reach the brain
6. brain process the impulses
7. you feel the object touching your heel
2)
Nerves
Spinal cord
Brain
The nervous system is made of central nervous system and peripheral nervous system. The peripheral nervous system is made of the network of nerves. The central nervous system is the brain and spinal cord that will receive impulse and send a response afterward. While brain could send the various signal, spinal cord could only send responses for reflexes.
3)
a. the diagram is showing Neuron cell
The nervous system is made up of multiple neuron cells. The neuron cells are specialized in sending a signal. It has a long axon that could deliver the signal far away. The signal is only one way though, so you will need a different neuron for receiving receptor signal and sending a response signal.
b. Two missing labels in the picture would be: axon.
It seems both of the label pointing out to the axon of the nerve cell. Since both of it pointing the same neuron cell, it should have the same name. Axon has a role in delivering nutrient and signal across the body.
c. Myelin sheath will allow the signal to run faster. This will help in a process that needs speed like reflexes. The sheath will cover a part of the neuron and prevent the ion exchange. Myelin sheath stop in some part called node of Ranvier. This will allow the action potential to "leap" from node to node, make it travel much faster.
