The time it takes the Earth to rotate once is called a day (24 hours). The actual rotation time is a little less, about 23 hours and 56 minutes. But the solar day is longer, almost exactly 24 hours, because of the distance the Earth moves in its orbit around the Sun.
Connective tissue is present in all muscles as fascia. Enclosing each muscle is a layer of connective tissue known as the epimysium; enclosing each fascicle is a layer called the perimysium, and enclosing each muscle fiber is a layer of connective tissue called the endomysium.t is one of three major muscle types, the others being cardiac muscle and smooth muscle. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. Skeletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers.
consists of areolar connective tissue and adipose tissue, and may also be referred to as the  subcutaneous layer  of the skin. is more relevant to the study of muscle structures because it is deep fascia that holds the muscles together. It consists of dense fibrous connective tissue. general example of the structure of muscle and associated tissues is shown below. Above: Diagram of the Structure of Muscle (and associated connective tissue). Periosteum. Periosteum is the outer layer of bone (as illustrated below).
