236 Tubal tonsil (human)Stain: Azan. The tubal tonsil consists of a collection of lymphoid nodules near the auditory tube opening and forms part of the Waldeyers ring of defense in the nasopharyngeal cavity. This tonsil has fewer crypts (1), and the surface is covered by one to more layered ciliated epithelium (2).

(B) After dissection of a complete mole grape-like aggregations of dilated chorionic villi are presented as numerous liquid-filled vesicles (1) varying in diameters (from few mm up to 1 cm) surr...placenta; trophoblast; hydatiform molePoja Histology Collection - Placenta
238 Trophoblast cell in lung alveolar interstitium (human, early midpregnancy)Stain: Hematoxylin-eosin. It is well known that free circulating trophoblast cells can be found migrated into lung parenchyma during normal pregnancy. In this sample a large trophoblast cell (→) is localised within the normal alveolar interstitium. Alveolar phagocytes (*) are present in the alve...placenta; trophoblast; lungPoja Histology Collection - Placenta
239 Uvula (soft palate, human)Stain: Azan. Detail of the uvula at the nasal side shows the border between the non-keratinized stratified squamous epithelium (right, oral side) and pseudostratified columnar epithelium (left, nasal side). The lamina propria is composed of dense connective tissue. At the bottom part of a blood-fil...oral cavity; lining mucosaPoja Histology Collection - Oral Cavity Subset
240 Uvula (soft palate, human; low magnification)Stain: Azan. At the right (oral side, non-keratinized stratified squamous epithelium); at the left (nasal side, same epithelium). In the submucosa mainly mucous uvular glands are localized. At the bottom, striated muscle of the uvular muscle. The uvular tip is richly vascularized.oral cavityPoja Histology Collection - Oral Cavity Subset

244 Cranial Nerve Exam: Abnormal Examples: Cranial Nerves 9 & 10 - Sensory & Motor: Gag ReflexUsing a tongue blade, the left side of the patient's palate is touched which results in a gag reflex with the left side of the palate elevating more then the right and the uvula deviating to the left consistent with a right CN 9 & 10 deficit.

245 Cranial Nerve Exam: Abnormal Examples: Smooth PursuitThe patient shown has progressive supranuclear palsy. As part of this disease there is disruption of fixation by square wave jerks and impairment of smooth pursuit movements. Saccadic eye movements are also impaired.

247 Cranial Nerve Exam: Abnormal Examples: VergenceLight-near dissociation occurs when the pupils don't react to light but constrict with convergence as part of the near reflex. This is what happens in the Argyll-Robertson pupil (usually seen with neurosyphilis) where there is a pretectal lesion affecting the retinomesencephalic afferents controllin...Cranial Nerve ExaminationNeuroLogic Exam: An Anatomical Approach

250 Cranial Nerve Exam: Abnormal Examples: Cranial Nerves 9 & 10 - Motor (x2)When the patient says ah there is excessive nasal air escape. The palate elevates more on the left side and the uvula deviates toward the left side because the right side is weak. This patient has a deficit of the right 9th & 10th cranial nerves.
