2. Bundle branch block - Wikipedia

   en.wikipedia.org/wiki/Bundle_branch_block

   Tachycardia-dependent bundle branch block; A simple way to quickly differentiate between the two types is to note the deflection of the QRS complex in the V1 lead. A (V1) QRS segment deflected down indicates left bundle branch block, while a deflection up indicates right bundle branch block. In both types, the QRS is wide (> 0.12 seconds).

3. Study of animal locomotion - Wikipedia

   Stride range of motion: the leg's integrated path between stance onset and swing offset. Joint angles: Walking can also be quantified through the analysis of joint angles. [10] [11] [12] During legged locomotion, an animal flexes and extends its joints in an oscillatory manner, creating a joint angle pattern that repeats across steps. The ...

4. Motor control - Wikipedia

   en.wikipedia.org/wiki/Motor_control

   Model systems have also demonstrated the role of central pattern generators in driving rhythmic movements. [14] A central pattern generator is a neural network that can generate rhythmic activity in the absence of an external control signal, such as a signal descending from the brain or feedback signals from sensors in the limbs (e.g ...

5. Glasses - Wikipedia

   en.wikipedia.org/wiki/Glasses

   Reading glasses are available without prescription from drugstores, and offer a cheap, practical solution, though these have a pair of simple lenses of equal power, and so will not correct refraction problems like astigmatism or refractive or prismatic variations between the left and right eye. For the total correction of the individual's sight ...

6. Ashman phenomenon - Wikipedia

   en.wikipedia.org/wiki/Ashman_phenomenon

   Ashman beats are described as wide complex QRS complexes that follow a short R-R interval preceded by a long R-R interval. [3] This short QRS complex typically has a right bundle branch block morphology and represents an aberrantly conducted complex that originates above the AV node, rather than a complex that originates in either the right or left ventricle.

7. Surface anatomy - Wikipedia

   Anatomists divide the lower limb into the thigh (the part of the limb between the hip and the knee) and the leg (which refers only to the area of the limb between the knee and the ankle). The thigh is the femur and the femoral region. The kneecap is the patella and patellar while the back of the knee is the popliteus and popliteal area.
