Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct

Extracerebral vessels‚ located at the base and surface of the brain‚ are innervated by perivascular nerves originating from the superior cervical ganglion‚ responsible for the sympathetic innervation‚ the sphenopalatine and otic ganglia‚ mainly supplying parasympathetic nerves‚ as well as the trigeminal ganglion [59]. This extrinsic innervation is lost‚ when perforating arteries enter the brain. These parenchymal arterioles have unique properties compared to the microvasculature found in other organs;

You can call them specialized cells in which includes the units of info-development in our brain‚ are very responsible for the perception and the transportation of information. Each part of the neuron has a very important role providing information in the whole body. The most important parts of a neuron are: a cell body‚ dendrites‚ and an axon. • Cell Body‚ also

There are three main nerves in your hand radial nerve‚ median nerve‚ and ulnar nerve. Each one of these gives movement and feeling to different areas of the hand. The ulnar nerve is one of the three main nerves in your arm. It travels from your neck down into your hand. The most common place for this nerve is behind the inside part of the elbow. The radial nerve descends down the arm with in the triceps with in the upper arm. Then moves down the arm within the humerus also known as the radial

Stimulus-Dependent Lab A motor unit is a motor neuron and the muscle fiber it controls. A whole muscle is made up of hundreds of motor units that are handled by different motor neurons that react at different levels of stimulation. The electric shock acts as an action potential by changing the membrane permeability allowing the sodium and potassium ions to pass through. At different levels of stimulation the motor neurons stimulate a motor unit and the more stimulation the more motor units become
