Q. What do the acinar cells produce? What do the islets of Langerhans produce? Q. What is the approximate ratio of exocrine tissue to endocrine tissue?

ngs. QUESTION 25 What is the difference between ballistic and proprioceptive neuromuscular facilitation (PNF)? Ballistic stretching involves moving quickly, bouncing, or using momentum to produce a stretch. This type of stretch is often viewed as necessary for sport movements and should be reserved for coaching and conditioning athletes and not used in general physical education. An example would be bouncing down repeatedly to touch the toes. Proprioceptive Neuromuscular Facilitation (PNF) is a static stretch using combinations of active and passive stretching techniques. This specialized static stretch uses a contraction-relaxation combination of movements, taking advantage of reflexes and neuromuscular principles to relax the muscles being stretched. Proprioceptive Neuromuscular Facilitation (PNF) involves moving quickly, bouncing, or using momentum to produce a stretch. This type of stretch is often viewed as necessary for sport movements and should be reserved for coaching and…
