PediNeuroLogic Exam: Newborn: Normal: Tone - Popliteal Angle
The popliteal angle is an assessment of the tone of the hamstring muscles. It is done one leg at a time. The thigh is flexed on the abdomen with one hand and then the other hand straightens the leg by pushing on the back of the ankle until there is firm resistance to the movement. The angle between the thigh and the leg is typically about 90 degrees. Extension of the leg beyond 90 to 120 degrees would be seen in hypotonia. A neuroscience tutorial focusing on those aspects of the pediatric neurol

9 Wildebeest migration
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.
