The ulnar nerve is formed from the medial cord nerve roots of C7-T1. Originating in the brachial plexus‚ it descends down the arm before passing around the medial epicondyle of the elbow (the so-called funny bone) and then passes between the heads of flexor carpi ulnaris (FCU). It gives some cutaneous branches just before the wrist whilst the motor branches pass around the hook of hamate. Its motor contribution is to all small muscles of the hand except the lateral two lumbricals as well as FCU

septa that traverse the nerve and separate fascicles from one another. | | Single myelinated axon | Normal nerve | Axons thicker than one micron in the CNS and peripheral nervous system (PNS) are myelinated. Myelin is a spiral sheet of cell membrane wrapped around the axon. In the CNS‚ myelin is produced by oligodendroglial cells and in the PNS by Schwann cells. Each oligodendrocyte makes multiple segments of myelin that wrap around many axons. Each Schwann cell makes one segment of myelin.

As long as you are alive‚ your body will constantly metabolize organic molecules and produce waste products. If you can not get rid of these metabolic waste products‚ they will accumulate to toxic levels and poison your body. The urinary system is very important because it perform the essential function of getting rid of these metabolic wastes. Main Structures of the Urinary System The main structures that make up the urinary system are two kidneys (contains nephrons)‚ two ureters‚ one bladder‚ one

The cells in the baso lateral side of the ascending part of loop of Henley contain sodium/potassium ATP ase‚ these constantly remove NA+ and accumulate K+. The Na+ and K+ carrier protein (Sodium/potassium cotransporter) is present on the luminal membrane of the ascending part of loop of Henley. This carrier protein will transport 1 Na+‚ 1 K+ and 2 Cl- into cells. This part of the nephron is water impermeable.
