The brow ridge is a nodule or crest of bone situated on the frontal bone of the skull. It forms the separation between the forehead portion itself (the squama frontalis) and the roof of the eye sockets (the pars orbitalis). Normally, in humans, the ridges arch over each eye, offering mechanical protection.
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
A sebaceous cyst is a term commonly used to refer to either: [1]. Epidermoid cysts (also termed epidermal cysts, infundibular cyst); Pilar cysts (also termed trichelemmal cysts, isthmus-catagen cysts)
Thyroglossal cyst usually presents as a midline neck lump (in the region of the hyoid bone) that is usually painless, smooth and cystic, though if infected, pain can occur. There may be difficulty breathing, dysphagia (difficulty swallowing), or dyspepsia (discomfort in the upper abdomen), especially if the cyst becomes large.
The supraorbital foramen is a small groove at superior and medial margin of the orbit in the frontal bone. It is part of the frontal bone of the skull. [2] It arches transversely below the superciliary arches and is the upper part of the brow ridge.
Micrograph of a brown tumor (left of image). H&E stain.. Brown tumours consist of fibrous tissue, woven bone and supporting vasculature, but no matrix.The osteoclasts consume the trabecular bone that osteoblasts lay down and this front of reparative bone deposition followed by additional resorption can expand beyond the usual shape of the bone, involving the periosteum thus causing bone pain.
Exostoses can cause chronic pain ranging from mild to debilitatingly severe, depending on the shape, size, and location of the lesion. It is most commonly found in places like the ribs, where small bone growths form, but sometimes larger growths can grow on places like the ankles, knees, shoulders, elbows and hips.
The corrugator supercilii muscle acts upon the skin of the forehead superior to the middle of the supraorbital margin, [1] drawing the eyebrow inferomedially to produce vertical wrinkles of the forehead [3] just superior to the nose. [1] It is the "frowning" muscle, and may be regarded as the principal muscle in the expression of suffering. [4]
