Neurulation Development of the Central Nervous System Diagram

Neurulation forms the CNS from neural plate (ectoderm thickening) folding into neural groove, then neural tube by fusion of neural folds. Anterior neuropore closes first (day 25), posterior last (day…

The Spinothalamic Tracts Ascending Sensory Diagram

The spinothalamic tracts carry pain, temperature, and crude touch from the body: lateral for pain/temp, anterior for touch/pressure. Fibers cross in the spinal cord shortly after entry, ascend contralaterally to…

Course of the Lateral Cutaneous Nerve of the Forearm Diagram

Lateral cutaneous nerve of forearm (from musculocutaneous) supplies lateral forearm skin, running with cephalic vein. Its sensory only.

Bones

Articulations and Parts of the Sternum Diagram

Sternum parts: manubrium (superior, clavicular notches), body (middle, costal notches), xiphoid (inferior, cartilaginous in youth). Manubriosternal joint (angle of Louis) at T4/5 level.

Organs

The Hard and Soft Palate Diagram

Hard palate (maxilla/palatine bones) forms anterior roof of mouth; soft palate (muscular: tensor/levator veli palatini, palatoglossus/pharyngeus) hangs posteriorly with uvula. It separates oral/nasal cavities during swallowing.

Anatomical Course of the Inferior Alveolar Nerve and Lingual Nerve Diagram

Inferior alveolar nerve (V3 branch) enters mandibular foramen, runs in canal supplying lower teeth, exits as mental nerve for chin/lower lip; lingual nerve (also V3) supplies anterior tongue sensation/floor of…

Aorta Diagram

The aorta begins at left ventricle (ascending), arches leftward (arch with three branches), descends thoracic then abdominal to bifurcate at L4 into common iliacs. It supplies all systemic arteries except…

Anatomy of the Nerves of the Dorsum of the Foot Superficial and Deep Fibular Nerves Diagram

Nerves of dorsum foot include superficial fibular (sensory to dorsum except first webspace), deep fibular (first webspace skin, extensor digitorum brevis), sural (lateral foot). They emerge from anterior/lateral leg compartments.

Medical

Anatomical Course of the Common Fibular Nerve and its Terminal Branches Diagram

The common fibular (peroneal) nerve wraps around fibular neck (vulnerable to injury), divides into superficial (lateral compartment, peroneus longus/brevis) and deep (anterior compartment, tibialis anterior, extensors) branches. It supplies dorsiflexion,…
