Clinical significance
The cubital fossa is clinically important for venepuncture and for blood pressure measurement.When the arm is fractured this may refer to a fracture of the humerus bone. Veins on the arm may be taken when a coronary artery bypass graft is needed. Other animals
In other animals, the term arm can also be used for homologous or analogous  structures (such as one of the paired forelimbs of a four-legged animal or the arms of cephalopods, respectively). In anatomical usage, the term arm may sometimes refer specifically to the segment between the shoulder and the elbow, while the segment between the elbow and wrist is the forearm. However, in common, literary, and historical usage, arm refers to the entire upper limb from shoulder to wrist. This article uses the former definition; see upper limb for the wider definition.In primates the arm is adapted for precise positioning of the hand and thus assist in the hands manipulative tasks. The ball and socket shoulder joint allows for movement of the arms in a wide circular plane, while the structure of the two forearm bones which can rotate around each other allows for additional range of motion at that level.

Tobramycin/dexamethasone, sold under the brand name Tobradex, is a fixed-dose combination medication in the form of eye drops and eye ointment, marketed by Alcon. The active ingredients are tobramycin (an antibiotic) and dexamethasone (a corticosteroid). It is prescribed for the treatment of pink eye in combination with bacterial infections. Contraindications
It is contraindicated with herpetic and other viral eye infections. Other contraindications include fungal and mycobacterial infections because tobramycin is inactive against those, and the corticoid acts as an immunosuppressive agent, preventing the bodys immune system from dealing with the infection. The drops are also contraindicated in patients with corneal lesions. Side effects
Similarly to other corticosteroid eye drops, side effects include hypersensitivity and, especially after long-term use, secondary eye infections, cataract (clouding of the eye lens) and increased intraocular pressure, leading to glaucoma. Consequently, the drug should not be applied longer than 24 days without further medical evaluation. Interactions
Anticholinergic eye drops potentiate the risk of increased intraocular pressure. Systemic aminoglycoside antibiotics increase toxicity for ears, nerves and kidney. Brand names
Tobrason is a brand name in Jordan. References
