Covered by: Tunica albuginea (dense CT). Structural unit: Seminiferous tubules lined by germinal epithelium (spermatogonia → sperm). Supporting cells: Sertoli cells (tcolumnar epithelium with long stereocilia. Circular smooth muscle in wall. Lumen: irregular, lined by pseudostratified columnar epithelium with stereocilia. Thick muscular coat (inner longitudinal, middle circular, outer longitudinal). Tubuloalveolar, lined by simple columnar to pseudostratified epithelium. Surro...

Endometrium: Lined by simple columnar epithelium with ciliated & secretory cells. Myometrium: Thick smooth muscle (inner longitudinal, middle circular/oblique, outer longitudinal). Perimetrium: Outer serosa/adventitia. Endocervix: Lined by simple columnar epithelium with mucous-secreting glands. Ectocervix: Lined by non-keratinized stratified squamous epithelium (like vagina). Transformation zone: Junction between columnar & squamous epithelium (common site for cervical carcinoma...

Description: Outer covering: Germinal epithelium (simple cuboidal). Tunica albuginea: Dense connective tissue beneath epithelium. Cortex: Contains ovarian follicles (primordial → primary → secondary → Graafian). Medulla: Loose connective tissue, blood vessels, lymphatics, nerves. Corpus luteum and corpus albicans may be present depending on cycle.

Lens: avascular, made of lens fibers arranged concentrically. Aqueous humor & vitreous body: maintain intraocular pressure & transparency. Neural coat (innermost): retina. Retina layers: 10 layers from pigment epithelium to nerve fiber layer. Vascular coat (middle): choroid, ciliary body, iris. Choroid: highly vascular, pigmented melanocytes.Iris

3. Inner Ear (Cochlea + Vestibular System) Cochlea: Has Organ of Corti on basilar membrane with hair cells (sensory) + supporting cells. 3. Inner Ear (Cochlea + Vestibular System) Cochlea: Has Organ of Corti on basilar membrane with hair cells (sensory) + supporting cells. Vestibular apparatus (utricle, saccule, semicircular canals): lined by simple cuboidal epithelium, contain sensory hair cells + otoliths (in utricle/saccule). 1. External Ear (Auricle + External Auditory Canal) ...

Posterior Triangle of the Neck: boundaries, contents, subdivisions, and clinical points. Anterior Triangle of the Neck: boundaries, subdivisions, and applied anatomy. Submental Triangle: borders, floor, contents. Digastric (Submandibular) Triangle: boundaries, contents, clinical relevance. Carotid Triangle (Scleroti...

This document covers concise and clinically important notes about: Ansa Cervicalis (Cervical Plexus loop): formation, roots, branches, and muscles supplied. Tonsillar / Pharyngeal (Calyx) Region: structure, boundaries, important points. Temporal (Temple) Anatomy: arterial supply, venous drainage, and nerve supply. Arterial, Venous, and Nerve Supplies: simplified tables of head & neck structures for quick recall. Designed in a clear, point-wise format with important diagrams, mne...

Lacrimal apparatus Highly useful for MBBS, BDS, Physiotherapy, and Allied Health students. Temporal Fossa – boundaries, contents, clinical importance. Infratemporal Fossa – boundaries, contents, pterygoid muscles, maxillary artery, venous plexus, and applied anatomy. Cortex (related functional areas) – motor, sensory, auditory, and visual cortex (concise points). Important Ganglia – locations, connections, and applied anatomy.

These notes are highly useful for MBBS, BDS, Physiotherapy, and Allied Health sciences students. This document provides clear and concise notes on: Otic Ganglion – location, roots, connections, fibers carried, and clinical importance. Temporomandibular Joint (TMJ) – type of joint, articular surfaces, capsule, ligaments, movements, muscles involved, and applied anatomy (dislocation, arthritis, TMJ disorders). Diagrams & flowcharts for quick revision.
