Nevus araneus (spider nevus): in the center of the redĀ lesionĀ a small (1 mm) redĀ papuleĀ is visible, surrounded by several distinct radiatingĀ vessels. Pressure on the lesion causes it to disappear, however blanching is replaced by rapid refill from the centralĀ arterioleĀ when pressure is released.

TheĀ spinal cordĀ is a long, thin, tubular structure made up ofĀ nervous tissue, which extends from theĀ medulla oblongataĀ in theĀ brainstemĀ to theĀ lumbarĀ region of theĀ vertebral column. It encloses theĀ central canalĀ of the spinal cord, which containsĀ cerebrospinal fluid. TheĀ brainĀ and spinal cord together make up theĀ central nervous systemĀ (CNS). The spinal cord begins at theĀ occipital bone, passing through theĀ foramen magnumĀ and entering theĀ spinal canalĀ at the beginning of theĀ cervical vertebrae. The spinal cord extends down to between the first and secondĀ lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord.
There are 31 spinal cord nerve segments in a human spinal cord:
ā¢ 8 cervical segments forming 8 pairs ofĀ cervical nerves
ā¢ 12 thoracic segments forming 12 pairs ofĀ thoracic nerves
ā¢ 5 lumbar segments forming 5 pairs ofĀ lumbar nerves
ā¢ 5 sacral segments forming 5 pairs ofĀ sacral nerves
ā¢ 1 coccygeal segment

TheĀ maxillary arteryĀ supplies deep structures of the face. It branches from theĀ external carotid arteryĀ just deep to the neck of the mandible.
The maxillary artery, the larger of the two terminal branches of theĀ external carotid artery, arises behind the neck of theĀ mandible, and is at first imbedded in the substance of theĀ parotid gland; it passes forward between theĀ ramus of the mandibleĀ and theĀ sphenomandibular ligament, and then runs, either superficial or deep to theĀ lateral pterygoid muscle, to theĀ pterygopalatine fossa.
It supplies the deep structures of the face, and may be divided intoĀ mandibular,Ā pterygoid, andĀ pterygopalatineĀ portions.
