Anatomy Consists of a ridge. Begins faintly anteriorly where it begins at mental tubercle (chin), more evident as it courses back and up to become continuous with anterior border ramus. Clinical Attachment for depressor anguli oris, quadratus labii inferioris. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy The perpendicular part of the mandible, its upper extremities consisting of the coronoid and condylar processes, with the mandibular notch between. Laterally, almost fully covered by masseter; postero-medially, pterygoid. Clinical The mandible (jawbone) holds the lower teeth. Chews. involved in speech. Along with cranium, makes up skull. Four parts (each side): Anterior (left and

Anatomy Branch of the facial nerve (also known as the seventh cranial nerve). Facial nerve: Has a motor and sensory origin that join together to form the nerve. It passes through the internal auditory meatus through the facial canal and finally exits from the stylomastoid foramen, and into the parotid gland where it divides into

Anatomy Origin: Radial and palmar aspects of the flexor digitorum profundus tendons. Insertion: Lateral aspect of extensor apparatus of index, middle, ring and little fingers. Functions Extension of interphalangeal joints while flexing metacarpophanalgeal joint. Supply Nerve Supply: -Medial two: Deep branch of the ulnar nerve (C8, T1) -Lateral two: Digital branches of the median nerve

Anatomy Centre of nearer row of carpal bones, crescent-shaped. Articulates up with radius, down with capitate and hamate, in with triquetral, out with scaphoid (scaphoid is other carpal that articulates with radius). Clinical Most frequently dislocated carpal bone. Kienbock’s disease; avascular necrosis, cause unclear, rare. Interested in taking our award-winning Pocket Anatomy app for a

Anatomy Paired thoracic respiratory organs, right 3 lobes, left 2 (heart accommodated), in closed pleural cavities, separated by mediastinum, diaphragm below, thoracic inlet (T1, 1st ribs, manubrium) above, surrounded by thoracic cage (T1-12, ribs, costal cartilages, sternum). Hilum; artery, vein, bronchus. Trachea divides left and right bronchi, continues in lung: main bronchus – lobar (3R,

Anatomy Big, wide vertebra (bodies progressively bigger C1 – L5), cylindrical, upper and lower surfaces flat or somewhat concave. Articulates with vertebrae above and below through fibrocartilaginous discs that allow some vertebral movement and provide shock absorption. No articular facets (unlike those on thoracic for articulation with ribs). No transverse foramina (unlike cervical). Clinical Significant

Anatomy Strong pedicles project posteriorly from either side of the back of the vertebral body, joining strong laminae which themselves meet at the midline (from where a spinous process projects back and down) to complete the neural arch (enclosing the vertebral foramen, bigger than thoracic, smaller than cervical). Where pedicle meets lamina each side, a

Anatomy Strong pedicles project posteriorly from either side of the back of the vertebral body, joining strong laminae which themselves meet at the midline (from where a broad, thick spinous process projects back and down) to complete the neural arch (enclosing the vertebral foramen, bigger than thoracic, smaller than cervical).

Anatomy Strong pedicles project posteriorly from either side of the back of the vertebral body, joining strong laminae which themselves meet at the midline (from where a spinous process projects back and down) to complete the neural arch (enclosing the vertebral foramen). Where pedicle meets lamina each side, a long thin transverse process, to which
