KNEE ARTHROSCOPY Procedure Steps: 1. The surgeon marks the anteromedial and anterolateral joint lines and portal positions with a skin marker. 2. The skin areas for portal placement are infiltrated with local epinephrine. If the knee has an effusion‚ the surgeon aspirates it with a 16-gauge needle on a 60ml syringe‚ followed by injection of a small amount of distending fluid. 3. After a small stab incision with a #11 or #15 knife blade‚ the surgeon inserts the irrigation cannula and trocar

Chapter 15 Signal Transduction 1) Endocrine‚ paracrine ‚ autocrine signaling‚ and cell-cell contact (Fig. 15-2). Endocrine signaling is long distance signaling. An example would be pancreatic cells secreting insulin. Paracrine signaling is for close proximity. An example would be a nerve cell releasing neurotransmitters. In autocrine signaling the cell that produces the ligand also contains the receptor for that ligand. This is how cancer cells work. In signaling by plasma membrane attached

The capstone meant to demonstrate the knowledge that students gained throughout the four years of attending Southwest Career & Technical Academy. The objective of this capstone was to find a prominent problem in the local community that is related to the experiences from the program areas. A prominent problem in the valley is asthma and the possible attacks that can be lethal if necessary precautions are not taken. People with or without asthma should be informed of the do’s and do not’s of taking

Electrical Stimulation Activity 1: Direct Heart Stimulation 1. Did you see any change in the trace? No change in the trace 2. Why or why not? This is because it needs more simulation 3. Did you see any change in the trace? I did see a change in the trace 4. Why or why not? There is double stimulation 5. Describe the change you see in the trace. How does it differ from the baseline trace? The trace increased from the baseline trace 6. What effect do the repeated stimuli

Introduction: When the body exercises‚ it uses two types of fuel‚ carbohydrates‚ and fatty acids. At the beginning of exercise the main source of fuel is carbohydrates‚ however the duration of the exercise progresses the carbohydrates deplete and fatty acids are needed to maintain the exercise. The type of fuel being used can be seen in the ratio called‚ respiratory exchange rate‚ or RER. An RER of 0.7 means that carbohydrates are being used for fuel‚ and a ratio of 1.0 means that only fatty acids

administered by the anesthesiologist. The patient right ear‚ facial region‚ and neck region were prepped and draped in Thera surgical fashion. The initial part of the procedure consisted of using one percent of lidocaine with one and one hundred thousand epinephrine creating an ear block around the patient’s right ear. lidocaine was also injected into the conchal bowl for a total of 15 CC’s for the right ear block in the conchal bowl block. After this was done and aloud to sit‚ the lesion was excised towards

PHYSIOLOGY Transmembrane receptors composed of excitable G-proteins‚ which cross the cell membrane and link selectively with extra cellular ligands are called adrenoceptors. They are also termed as α-2 Adrenoceptor agonists α-2 adrenergic receptors. Three α-2 isoreceptors - α-2a‚ α-2b and α-2c of adreno receptor bind α-2 agonists and antagonists with similar rapport and share an amino acid composition homology of roughly 70 to 75%. The efficacy of sub receptor specific agonists that constrains deleterious
