The pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler's fossa) is a small recess on either side of the laryngeal inlet. It is bounded medially by the aryepiglottic fold, and laterally by the thyroid cartilage and thyrohyoid membrane. [1] The fossae are involved in speech.
For many biologics (e.g., monoclonal antibodies), injection site reactions are the most common adverse effect of the drug, and have been reported to have an incidence rate of 0.5–40%. [ 2 ] In trials of subcutaneous administration of oligonucleotides , between 22 and 100% of subjects developed reactions depending on the oligonucleotide.
The injection site must be cleaned before administering the injection, and the injection is then administered in a fast, darting motion to decrease the discomfort to the individual. The volume to be injected in the muscle is usually limited to 2–5 milliliters, depending on injection site. A site with signs of infection or muscle atrophy ...
Piriform cortex, a region in the brain; Piriformis muscle, a gluteal muscle Piriformis syndrome, a neuromuscular disorder in which the piriformis muscle compresses the sciatic nerve; Piriform sinus, piriform recess or piriform fossa, synonyms referring to one of the four sites of the hypopharynx
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). It is useful in several applications, such as for spinal anesthesia, chemotherapy, or pain management. This route is also used to introduce drugs that fight ...
Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). ... By using this site, ...
The greater sciatic foramen is an opening in the posterior human pelvis.It is formed by the sacrotuberous and sacrospinous ligaments.The piriformis muscle passes through the foramen and occupies most of its volume.
The most common site of insertion is the antero-medial aspect of the upper, proximal tibia as this site lies just under the skin and is easily located. Other insertion sites include the anterior aspect of the femur , the superior iliac crest, proximal humerus , proximal tibia, distal tibia and the sternum (manubrium). [ 1 ]
