The saddle gullet is the cutout or tunnel underneath the fork and rides over the horse's withers. The design of the fork and the angle of the bars of the saddle tree determine the width and height of the gullet. It's important that the gullet have the right amount of clearance over the withers. If the gullet height is too short, the saddle will rub on the horse's withers. If the gullet width is too wide, the saddle will sit too low on the shoulders, and also rub on the horse's withers. Rubbed withers equals unhappy horse. A good rule of thumb to use for gullet fit is that there should be clearance of two to four fingers-widths between the withers and the gullet.
Network of protein fibers that provides structural support; aides in cell movement and movement of vesicles within the cell endoplasmic reticulum Extensive network of membrane-bound tubules and sacs that can be classified as rough or smooth; continuous with the nuclear envelope; provide compartments and surface area for reactions to occur
The appendicular skeleton, which is attached to the axial skeleton, is formed by the pectoral girdles, the pelvic bone and the bones of the upper and lower limbs. The skeleton has six primary functions. They are support, protection, movement, mineral homeostasis, blood cell production, and storage. The skeletal system is the framework of the body which supports the body and maintains itâs shape. The pelvis, along with ligaments and muscle, provide a floor for the pelvic structures. Without the rib cages, costal cartilages, and intercostal muscles, the lungs would collapse. The skeleton supports the softer tissue and provides a point of attachment for skeletal muscles. Some bones provide leverage for movement.
