The scalp is the area of the head where head hair grows. It is made up of skin, layers of connective and fibrous tissues, and the membrane of the skull. Anatomically, the scalp is part of the epicranium, a collection of structures covering the cranium. The scalp is bordered by the face at the front, and by the neck at the sides and
the cranium (8 bones: frontal, 2-parietal, occipital, 2-temporal, sphenoid, ethmoid), and; the facial bones (14 bones: 2-zygomatic, 2-maxillary, 2-palatine, 2-nasal, 2-lacrimal, vomer, 2-inferior conchae, mandible). The occipital bone joins with the atlas near the foramen magnum, a large hole at the base of the skull. The atlas joins with the ...
The frontal bone has a number of parts, including the squamous part, the orbital part, and the nasal parts. The frontal bone connects to the parietal bone at the coronal suture to shape the crown and sides of the skull. The two separate parietal bones are joined at the sagittal suture, ensuring the crown is stable. [4]
Image of base of the skull with several of the foramina labeled. The human skull has numerous openings , through which cranial nerves, arteries, veins, and other structures pass. These foramina vary in size and number, with age. [1] [2]
Anatomy of the human head. 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 ...
The nerves descend in the posterior triangle of the neck beneath the platysma muscle and the deep cervical fascia. [citation needed] Near the clavicle, the supraclavicular nerves perforate the fascia and the platysma muscle to become cutaneous. They are arranged, according to their position, into three groups—anterior, middle, and posterior.
The greater occipital nerve is a nerve of the head. It is a spinal nerve, specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2.It arises from between the first and second cervical vertebrae, ascends, and then passes through the semispinalis muscle.
In human anatomy, the forehead is an area of the head bounded by three features, two of the skull and one of the scalp. The top of the forehead is marked by the hairline, the edge of the area where hair on the scalp grows. The bottom of the forehead is marked by the supraorbital ridge, the bone feature of the
