Types of polyploidy There are mainly two types of polyploidy-autopolyploidy and allo(amphi)polyploidy. There are various types under each of these major divisions. 1. Autopolyploidy is the presence of multiple sets of chromosomes derived from a single genotype.
The two most popular tests for shoulder impingement are the Neer test and the Hawkins test. In the Neer test (below left), the examiner stabilizes the scapula while passively elevating the shoulder, in effect jamming the humeral head into the acromion. In the Hawkins test (below right) the examiner elevates the arm to 90 degrees of abduction and forces the shoulder into internal rotation, grinding the cuff under the subacromial arch.
SLR is a neural tension test that can be used to rule in or out neural tissue involvement as a result of a space occupying lesion, often a lumbar disc herniation. It is one of the most common neurological tests of the lower limb. The straight leg raise is a passive test. Each leg is tested individually with the normal leg being tested first. When performing the SLR test, the patient is positioned in supine without a pillow under his/her head, the hip medially rotated and adducted, and the knee extended.
