Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord.

Task 1- tissues Tissues are groups of similar cells which have a similar structure and function. All of these cells work together to complete various tasks. There are four different types of tissues in the human body that I am going to give examples of. These include the epithelial tissue‚ connective tissue‚ collagenous tissue and the nerve tissue. The first time of tissue is the epithelium tissue which has the function of helping to protect the body. There are four main types of epithelium tissues;

enabling the delicate nerve fibers to be seen (Marieb 9). A spinal cord injury can prompt a physician to order an MRI instead of a CT Scan (“Magnetic Resonance Imaging”). For instance‚ multiple sclerosis plaques within the spinal cord do not show up well in CT Scans‚ but are dazzlingly clear in an MRI (Marieb 9). Additionally‚ the MRI will check the discs and nerves of the spine for conditions such as bulging discs‚ herninated discs‚ or spinal tumors (“Magnetic Resonance
