Skull Bone Anatomy & Clinical Significances
Skull: The skull is a skeletal framework of the head of vertebrates, that supports the face and makes a protective cavity concerning the brain. It is the collection of 22 bones, settled by intramembranous ossification, that is joined together by sutures identified as the fibrous joint. These joints combine together in adulthood, therefore permitting brain …
Appendicular & Axial Skeleton Anatomy
The Human Skeleton can be divided up into two parts, the axial Skeleton, and the appendicular skeleton. The central part of the body contains the axial skeleton, and the bones lying along a central axis of the body are the appendicular skeleton.
Cervical Spine Anatomy & Clinical Significances

Shoulder Muscles : Attachment, Nerve Supply & Action
Shoulder Muscles: The shoulder muscles are associated with movements of the upper limb. The shoulder muscles produce the characteristic shape of the shoulder and can be classified into two groups: Extrinsic shoulder muscles – arise from the torso, and inserts to the clavicle, scapula or humerus). Intrinsic shoulder muscles – arise from the scapula and/or …
Foot Muscles : Attachment, Nerve Supply & Action
Foot Muscles: The muscles working on the foot can be distributed within the extrinsic and intrinsic muscles. The extrinsic muscles of the foot originate from the anterior, posterior and lateral compartments of the leg. The extrinsic muscles are largely responsible for eversion, inversion, dorsiflexion, and plantarflexion of the foot.The intrinsic muscles of the foot are …
