Coordination Exam: Normal Exam: Finger-to-nose (x2) (includes Spanish audio & captions) | The patient moves her pointer finger from her nose to the examiner's finger as the examiner moves his finger to new positions and tests accuracy at the furthest outreach of the arm.

Coordination Exam: Anatomy: Vestibulocerebellum (includes Spanish audio & captions) | The first subdivision of the cerebellum is the vestibulocerebellum. This consists of the connections between the vestibular system and the flocculonodular lobe. Dysfunction of this system results in nystagmus, truncal instability (titubation), and truncal ataxia.

Cranial Nerve Exam: Abnormal Examples: Cranial Nerve 5 - Sensory (x2) | There is a sensory deficit for both light touch and pain on the left side of the face for all divisions of the 5th nerve. Note that the deficit is first recognized just to the left of the midline and not exactly at the midline.

Gait Exam: Abnormal Examples: Hemiplegic Gait Demonstration | The patient has unilateral weakness and spasticity with the upper extremity held in flexion and the lower extremity in extension. The foot is in extension so the leg is too long therefore, the patient will have to circumduct or swing the leg around to step forward. This type of gait is seen with a U... | Gait Examination; Hemiplegic Gait | NeuroLogic Exam: An Anatomical Approach |

Cranial Nerve Exam: Abnormal Examples: Cranial Nerve 2 - Visual Acuity | This patient's visual acuity is being tested with a Rosenbaum chart. First the left eye is tested, then the right eye. He is tested with his glasses on so this represents corrected visual acuity. He has 20/70 vision in the left eye and 20/40 in the right. His decreased visual acuity is from optic ne... | Cranial Nerve Examination | NeuroLogic Exam: An Anatomical Approach |

Coordination Exam: Abnormal Examples: Toe-to-finger (x2) (includes Spanish audio & captions) | Same as finger-to-nose except for the lower extremities. For both the upper and lower extremities, it is important to always compare right versus left.

Dentinal tubules in longitudinal section of tooth - human, adult. Thin ground section, polarizing microscopy - optical axes of the polarizing plates are crossed at 60. | Slightly oblique section shows dentinal tubules depicted by brown-stained hollow fiber-like structures containing odontoblastic processes (Tomes' fibers) in a semi-three dimensional way. Numerous fine secondary branches of these processes are anastomosing with those of neighboring tubules. | oral cavity; Tomes' Fibers; dentinal tubules | Poja Histology Collection - Oral Cavity Subset |
