Organelle RAFT Writing Assignment There are multiple organelles in The Cell Body Corporation, and many of them have very important jobs. The cell with the most important job is the nucleus. The nucleus is the main control center for the cell. Without it the other organelles wouldn’t have jobs to complete. Information for the cell is stored within the nucleus.

Unit 7 Assignment 2: The Effects of Selected Drugs and Diseases on the Central Nervous System 1. The CNS otherwise known as the Central Nervous System is comprised of the brain which is continuous with the spinal cord. Since the CNS is made up of the brain and spinal cord it is protected by the hard bony skull and vertebral column. (Pages 418- 420) 2. The BBB also known as the Blood Brain Barrier which in conjunction with the Cerebrospinal Fluid or CSF is what nourishes and protects the cells of the CNS.
They convert energy into forms that are usable by the cell. Located in the cytoplasm, they are the sites of cellular respiration which ultimately generates fuel for the cells activites. Mitochondria are also involved in other cell processes such as cell division and growth. A typical animal cell will have 1000-2000 mitochondria, so the cell will be capable of producing a high amount of available energy. Some cells have more energy that others, your fat cells have lots more mitochondria because they store a lot of energy.
Week 5 Forum Student’s Name Institutional Affiliation Date The amygdala and hippocampus are the main parts of the brain whose responsibility is the regulation of memory. The amygdala is divided into two, the right and left hemispheres. The right hemisphere is responsible for negative emotions like fear and sadness while the left hemisphere induces both the pleasant and unpleasant emotions when stimulated. These hemispheres have independent memory systems but they work together to encode, store and interpret information. The hippocampus on the other side is responsible for the production of corticosteroids (chemicals that produce physiological responses to stimuli).
Nervous tissues are found is all organs in the body some have more than others thought, Maximum in the nervous system, least in fatty deposits. Some examples are brain which is a main nervous tissue but also an organ also the heart that is one of our most important organ but also a nervous tissue. Here’s a labelled picture of a nervous tissue; http://biologyonline.us/Online%20A&P/AP%202/Northland/AP2lab/Lab%201%20online/lab1/images/Picture14.jpg Epithetical tissue The function of the epithetical tissue include transportation of materials, protection of underlying tissues, absorption of water and nutrients and secretions of waste products. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers.
ch 12 review 1 what are the components of the CNS? The PNS? - CNS consists of the brain and spinal Cordially, PNS consists of all other nervous tissue 2 what is difference between afferent neurons and efferent neurons? Which one is associated with sensory neurons? With motor neurons?
The central nervous system the brain and spinal cord contain about 12 billion nerve cells/neurons. Assumptions – 2 – Behaviour is caused by the actions of the nervous system, the brain in particular. The approach considers behaviour as the consequence of a number of chemical and electrical reactions in our bodies. Bio-psychologists believe that there is a need to focus on the body internally to establish the reason for behaviour. Bio-psychologists believe that behaviour is hereditary and carried in the genes.
2 - The brain, along with the spinal cord, makes up the central nervous system, and it is this that controls all of our body’s functions. The brain is made up of cells. Within the brain there are billions of nerve cells that are known as neurons. These neurons communicate with each other and with other parts of the body by sending messages (impulses) via a system of nerve pathways. The brain sends signals to the body and to other parts of the brain in
