The sclera makes up roughly 83% of the fibrous layer of the eye.
There are three layers to the pericardium. They go in alphabetical order. The first layer is the Fibrous Pericardium. The second layer is the parietal pericardium and the third and innermost layer is the visceral layer.
The serous pericardium is a thin, double-layered membrane that covers the heart and consists of the parietal pericardium (outer layer) and visceral pericardium or epicardium (inner layer). The fibrous pericardium is a tough, fibrous layer that surrounds the serous pericardium and helps protect the heart and anchor it within the chest cavity.
The fibrous layer of a bone, also known as the periosteum, is a dense connective tissue that envelops the outer surface of bones, except at the surfaces of the joints. It serves several key functions, including providing attachment points for muscles and tendons, supplying blood vessels and nerves to the bone, and playing a role in bone growth and repair. The fibrous layer consists of collagen fibers that help anchor it firmly to the underlying bone.
Fibrous pericardium.
periosteum
it is composed of three layers:an outer cuticular layer,intermediate fibrous layer,and inner mucous layer. the cuticular layer is continued with the skin of external acoustic meaus; the fibrous layer lies b/w cuticular and mucous layer; the mucous layer is continued with the mucous membrane of tympanic membrane.
The outermost layer of the pericardial membrane is the fibrous pericardium. It is a tough, protective layer that surrounds the heart and helps anchor it in place within the chest cavity.
Fibrous pericardium and serous pericardium. The serous pericardium is made up of an outer parietal layer that is fused to the fibrous pericardium and an inner visceral layer (aka epicardium) that is a layer of the heart wall and adheres tightly to the heart.
The sac consists of two layers, the parietal (outer) and visceral (inner) layer
