Some peptide/ protein hormones (angiotensin II, basic fibroblast growth factor -2, parathyroid hormone-related protein) also interact with intracellular receptors located in the cytoplasm or nucleus by an intracrine mechanism.eptide hormones are produced by many different organs and tissues, however, including the heart (atrial-natriuretic peptide (ANP) or atrial natriuretic factor (ANF)) and pancreas (glucagon, insulin and somatostatin), the gastrointestinal tract (cholecystokinin, gastrin), and adipose tissue stores (leptin).
Foot-and-Ankle Group. While your core muscles control ski-specific balance, your foot-and-ankle muscle group takes responsibility for the edging, pressure and rotational movements used in skiing. Your feet have intrinsic and extrinsic muscles.
Work different muscle groups. Shoveling snow is a high-intensity workout â especially if you shovel fast â and it works all of your major muscle groups. You will feel it the next day in your legs, core, back, shoulders and arms. Use a full range of motion and fire your core muscles as you bend and lift. Use proper technique.
