Test 6 Flashcards
What is the direction of flow in the Transverse Sinus?
Laterally away from the confluence
What is the direction of flow in the Occipital Sinus
Superiorly towards Confluence
What is the direction of flow in the The Superior Petrosal Sinuses
Laterally and posteriorly towards the confluence
What is the direction of flow in the The Sigmoid Sinus
Inferiorly towards Confluence S bend
Describe the location of the cavernous sinuses
Either side of the Sphenoid body
Describe the location of the inferior petrosal sinuses
The inferior petrosal sinuses are two small sinuses situated on the inferior border of the petrous part of the temporal bone, one on each side. Each inferior petrosal sinus drains the cavernous sinus into the internal jugular vein.
Which sinuses meet at the confluence of sinuses
Superior Sagital Sinus, 2 x transverse sinus, straight sinus, occipital sinus
Describe location of Pyloric Sphincter both internally and in terms of surface location
Junction where stomach empties food into the small intestine- Duodenum. 3inches above belly button- just below xiphoid process and slightly to the right
Describe location of Ilio Caecal valve both internally and in terms of surface location
Junction between small intestine and large intestine. McBurneys point. One third of the way along a line from the right anterior superior iliac spine to the umbilicus (think RASIS)
What considerations would you think important in a patient with tension and spasm in the iIlio Caecal Valve
A Blockage Stress Apendicitus Solar Plexus (stress) Coeliac plexus- superior mesenteric. inferior mesenteric T10-L2- sympathetic supply Vagus Nerve
What underlying conditions would you suspect in a patient who reported anal bleeding
Colon Cancer Duodenal Ulver Haemoroids Constipation Crohns Disease
How would you approach the treatment of a patient with anal bleeding
Consult GP. Treat for stress.
How would differentiate different conditions of anal bleeding?
Colour of blood. Dark no oxgenated coming from Colon. Oxygenated more likely to be anal fissures/ tears
Where is the Pineal Gland located
Posterior superior margin of 3rd Ventricle
Where is the Thymus Gland located?
Behind the Sternum
