Answer:

1. sympathetic

2. parasympathetic

Explanation:

The sympathetic division of the autonomic nervous system triggers the release of stress hormones from adrenal medulla under emergency conditions. There is a series of physiological responses such as increased heart and breathing rate, an increased flow of blood to skeletal muscles, dilation of pupils, etc. These events helped Nasim to fight the stress conditions.  

Once she was relieved, the parasympathetic system is activated that shut down the physiological responses generated by sympathetic division. It slows down the breathing and heart rate and triggers the digestion and absorption of nutrients to restore the energy level of cells.

How does the structure of a brain cell related to its function?
lesya [120]

Solution:

Structure dictates function. Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (RNA).Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins.

The structure and shape of each type of human cell depends on what function it will perform in the body. For example, red blood cells (RBCs) are very small, flat discs, which allows them to easily fit through narrow capillaries and around sharp corners in the circulatory system to deliver oxygen throughout the body.

Neurons carry messages from the brain and spinal cord to the rest of the body, using electrical signals down their lengths and chemical signals between neurons. Since electrical signals travel much faster than chemical signals, neurons are long and thin to minimize the number of slower chemical signals that would be required between links in a chain of many shorter neurons.

The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.

And human sperm cells’ structures allow them to “swim” long distances to reach an egg for fertilization. They do this by using flagella, their long whip-like tails, and also by being very small, carrying little more than the DNA for a potential zygote.

This is the required answer.
