An interesting fact is that growers prefer sensimilla which is the name for cannabis plants that are not pollinated and do not have seeds. The structure of the female flower that is called glandular trichome produces resin on the flowers and leaves close to them.
A flexed knee is at about 140 degrees. It is a common misconception that 0-140 degrees is a normal range of motion, but most people have some hyperextension, too, taking their ROM into negative numbers. 1  normal ROM is usually minus 5 to 143 degrees in women.
As the knee is a synovial hinge joint, its function is to permit the flexion and extension of the lower leg relative to the thigh. The range of motion of the knee is limited by the anatomy of the bones and ligaments, but allows around 120 degrees of flexion.
