also featured in th phospholipid bilayers where they play a big part in diffusion etc. They are used as carrier to water soluble molecules‚ pumps wherby ATP is used to move water soluble molecules. Receptors are also proteins-these enable hormone and nerve transmittors to bind to specific cells‚ to the recognition sites as in enzymes. Glycoproteins act as receptors and recognition sites. Carrier proteins bind to a specific molecule‚ this inturn changes shape to get through the membrane surface to the

Axon: long tube like structure that conveys impulses away from the neurons cell body toward other neurons/muscles or glands 3. Cell Body: part of the neuron containing the cell nucleus as well as other structures that help the neuron carry out its functions; also known as the soma 4.

Cells are the structural and functional units of all living organisms; each specialised to perform dedicated duties throughout their life span. All living organisms can be sorted into one of two groups depending on the fundamental structure of their cells. These two groups are the prokaryotes and the eukaryotes. A Prokaryote cell is the first form of cells for many millions of years until the eukaryote cell evolved from the prokaryote cell‚ which created life. Prokaryote cells are organisms made

Muscles are responsible for all conscious and unconscious movement. It is how we move and react to an environment. There are three types of muscles in the body include the skeletal muscle‚ smooth muscle‚ and the cardiac muscle. Whether you are running‚ walking‚ breathing‚ eating‚ sleeping‚ or typing it all involves some sort of muscle action. Muscle cells that shape‚ form‚ and outline the whole human skeleton is called a muscle fibers. There are two types of muscle fibers: Type I (slow-twitching

Report 2 -Karthik raj Konnaiyan Patellar reflex: Patellar reflex is contributed by 3rd and 4th Lumbar segment nerves‚ in some cases 2nd lumbar segment is also involved. So an individual will be left with patellar reflex if these lumbar vertebrae are left intact. Patellar reflex is also called knee-jerk reflex as the names implies‚ it is involved with tapping of knee at certain point will cause a jerk movement. In medical terms when an individual is tapped on patellar tendon (area below the knee

BP increases. If a stimulus causes BP (controlled condition) to rise‚ the following sequence of events occurs (Figure 1-3). The higher pressure is detected by baroreceptors‚ pressure-sensitive nerve cells located in the walls of certain blood vessels (the receptors). The baroreceptors send nerve impulses (input) to the brain (control center)‚

CNS. Its main job is to get the information from the body and send out instructions. The peripheral nervous system is made up of all of the nerves and the wiring. This system sends the messages from the brain to the rest of the body. -The peripheral nervous system consists of the nerves that lie outside the brain and the spinal cord. These nerves carry impulses like sensations and information from the body to the spinal cord and from the spinal cord to the body. Thus‚ the peripheral nervous system
