Hyperechoic Vascular Plane: A Case Study

Arteries are a high pressure system and a pulse can be palpated. The muscle layer in arteries is stronger and they will not collapse like veins. Arteries are also deeper than veins and are surrounded by nerve endings, making arterial puncture painful.

4. Insert a probe into the aorta and observe where it connects to the left ventricle. Make an incision up through the aorta and examine the inside carefully for three small membranous pockets. These form the aortic semilunar valve which prevents blood from flowing back into the left ventricle.

Biceps Brachii - It's attachments are the coracoid process, supraglenoid tuberosity, and radial tuberosity. When it contracts it causes flexion and supination. It's located close to the endangerment site the antecubital. This area is known for housing chronic pain.

The vastus lateralis muscle forms part of the quadriceps muscle group of the upper leg and can be found on the anteriolateral aspect of the thigh. This muscle is more commonly used as the site for IM injections as it is generally thick and well formed in individuals of all ages and is not located close to any major arteries or nerves. It is also readily accessed. The middle third of the muscle is used to define the injection site. This third can be determined by visually dividing the length of the muscle that originates on the greater trochanter of the femur and inserts on the upper border of the patella and tibial tuberosity through the patella ligament into thirds. Palpation of the muscle is required to determine if sufficient body and mass is present to undertake the procedure.

Once inside the elbow the unlar nerveis recognized, lifted out, and moved to provide greater access to the joint. This is the "funny bone" nerve and it runs inside the ulnar groove.

The structure of neuromuscular junction consists of a neuron and skeletal muscle cell. The motor neurons, which arise from the spinal cord, supply the skeletal muscle fibers. The neuromuscular junction is un-myelin nerve with a bulb shape at the endings that contract the muscle fiber. The schwann cells form a covering over the postsynaptic membrane and nerve membrane of the fiber that is located under the terminal and is categorized as a post-junction folds. The area between the folds and the bulbs create the synaptic cleft. This consists of proteins and proteoglycans. The enzyme acetylcholinesterase; exist only at high levels in the synaptic basal lamina (UMN,

The physician inserts a tissue valve into the bigger artery there, and then takes the valve up to the

Medical staff will clean and shave your groin or arm for the insertion of the catheter. A local numbing agent will be administered, but you will be awake during the procedure. Medicines for anxiety could be given if patient is having trouble relaxing during the exam. Next, a small catheter will be inserted into an artery. The doctor then uses x-rays to guide the catheter to the area of interest. Once the catheter is in place, dye will be inserted through tube. This allows for visualization of your blood vessels. Very minimal movement will be aloud during this exam to ensure safety and high quality images. This procedure could last one to two hours. If this is a planned procedure and not an emergency, this is normally only scheduled in the

Discuss the different types of blood vessels. Include the different layers composing blood vessels (remember to include tissue types) in your discussion.

The superficial peroneal nerve runs under the peroneus longus muscle supplying the peroneus longus muscle and peroneus brevis muscle. It then continues down to the foot as a sensory nerve. The deep peroneal nerve runs under the peroneus longus muscle and extensor digitorum longus muscle, supplying the tibialis anterior muscle and peroneus tertius muscle. It emerges medial to the tibialis anterior muscle and runs with the anterior tibial vessels under the extensor

• A needle will be inserted into your arm to administer the IV contrast material.
