The material that makes up the membrane cell is the phospholipids, cholesterol, proteins, and carbohydrates.
The brain, heart and the skeleton are the integral parts of the nervous system, circulatory system and the skeletal system respectively. The nervous system is made of the brain and the spinal cord with neurons as the structural and functional units of it. The circulatory system is made up of the heart and its blood vessels. The skeletal system is made up of the bones and cartilages making the skeleton of the body.
The brain regulates the heart beat and the blood pressure. The heart nourishes the brain with oxygen and nutrients by pumping blood. The bone cells are nourished by the blood pumped by the heart. The bone marrow of the skeleton produces the new red blood cells which enter the blood circulatory system. Also the the ribs and the breast bone of the skeleton protects the heart, the cranium of the skeleton prtects the brain. The bones also provide calcium which is necessory for the functioning of the nervous system. The brain controls the skeletal movements of the body. The cerebellum of the brain controls the voluntary skeletal movements and the medulla controls the involuntary skeletal movements of the body. The blood brain barrier formed by the endothelial cells of the capillary walls located in the brain seperates the circulating blood from the brain and the extraclellular fluid in the central nervous system and acts as a selective semipermeable border.
the answer is A. because the roads are black and take in more light which makes the area hotter
Spinal nerves extending distal to the conus medullaris are collectively referred to as the Cauda equina. The correct option is e.
<h3>What is Cauda equina?</h3>
Cauda equina is the term used for all the spinal nerves and sacral nerves. These nerves are collectively called Cauda equina.
It is also a name for a disease where the nerve function of the bladder doesn't work properly and gets damaged. If the patient does not get treatment, he can get paralysis.
Thus, the Spinal nerves extending distal to the conus medullaris are Cauda equina. The correct option is e.
