The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament.
The human head consists of a fleshy outer portion, which surrounds the bony skull. The brain is enclosed within the skull. There are 22 bones in the human head. The head rests on the neck, and the seven cervical vertebrae support it. The human head typically weighs between 2.3 and 5 kilograms (5.1 and 11.0 lb) Over 98% of humans fit into this ...
Structures closer to the radius are radial, structures closer to the ulna are ulnar, and structures relating to both bones are referred to as radioulnar. Similarly, in the lower leg, structures near the tibia (shinbone) are tibial and structures near the fibula are fibular (or peroneal ).
Fascial spaces (also termed fascial tissue spaces [1] or tissue spaces [2]) are potential spaces that exist between the fasciae and underlying organs and other tissues. [3] In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection.
The following outline is provided as an overview of and topical guide to human anatomy: . Human anatomy is the scientific study of the morphology of the adult human.It is subdivided into gross anatomy and microscopic anatomy.
A radial plane is an anatomical plane that is used to describe a virtual slice along a radius of a somewhat cylindrical shaped body part. [1] The radial planes need not be perfectly drawn to overlap on an exact intersection point, particularly when the body part being sectioned is not a perfect cylinder, such as in the case of the maxilla and ...
The bicipital groove separates the greater tubercle from the lesser tubercle. [1] It is usually around 8 cm long and 1 cm wide in adults. [1] The groove lodges the long tendon of the biceps brachii muscle, positioned between the tendon of the pectoralis major muscle on the lateral lip and the tendon of the teres major muscle on the medial lip.
