ANATOMY

Detailed explanation-1: -The galea aponeurotica (also called the galeal or epicranial aponeurosis or the aponeurosis epicranialis) is a tough fibrous sheet of connective tissue that extends over the cranium, forming the middle (third) layer of the scalp.

Detailed explanation-2: -Epicranial Aponeurosis also referred to as the Galea Aponeurotica or the aponeurosis epicranialis is a broad tendon and is the intermediate section of the occipitofrontalis muscle. It runs from the superior portion of the frontal bone and covers the parietal bones to the lambdoid suture.

Detailed explanation-3: -A: aponeuroses are extensions of external tendons on the surface of pennate muscles that function as insertion sites for muscle fascicles and may play a role in modulating fascicle rotation and dynamic gearing during muscle contractions.

Detailed explanation-4: -The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays. Aponeuroses are structurally similar to tendons and ligaments.
