Overview of the Cerebrum Diagram

The cerebrum overview shows two hemispheres divided by longitudinal fissure, with frontal (planning, motor), parietal (sensory, spatial), temporal (auditory, memory), occipital (visual) lobes, plus insula deep in lateral sulcus and…

The Superficial Veins of the Upper Limb Cephalic and Basilic Veins Diagram

Superficial upper limb veins: cephalic (lateral, thumb to deltoid/axillary), basilic (medial, little finger to axillary), median cubital (connects cephalic/basilic at elbow). Theyre common IV sites.

Medical

Layers of the Thoracolumbar Fascia Diagram

Thoracolumbar fascia layers: anterior (psoas/quadratus lumborum), middle (between erector spinae/quadratus), posterior (covering erector spinae). They enclose paraspinal muscles, provide attachment for obliques/transversus.

Muscles

Hip Add Abd Diagram

The Hip Add Abd diagram (likely adduction/abduction) illustrates hip movements: adductors (magnus, longus, brevis, gracilis, pectineus) pulling the thigh medially, abductors (gluteus medius/minimus, tensor fasciae latae) moving it laterally. It…

Organs

Heart Wall

The heart wall has three distinct layers working together to pump blood tirelessly. The inner endocardium is smooth endothelium over connective tissue, preventing clots and providing a low-friction surface. The…

Medullary Pyramids Diagram

This Medullary Pyramids diagram (likely brainstem) depicts the ventral medulla oblongata with its paired pyramidal tractscorticospinal fibers descending to decussate at the pyramid level before continuing into the spinal cord…

Organs

Parts of the Parietal Pleura Diagram

Parts of parietal pleura: costal (chest wall), diaphragmatic (diaphragm), mediastinal (mediastinum), cervical (apex above first rib). Reflections form recesses (costodiaphragmatic deepest); fluid accumulates there in effusion.

Palmar View of the Thenar Muscles of the Thumb and Hand Labelled TeachMeAnatomy Diagram

Palmar view of thenar muscles shows abductor pollicis brevis (superficial), flexor pollicis brevis (superficial/deep heads), opponens pollicis (deep to abductor), all from flexor retinaculum/scaphoid/trapezium to thumb proximal phalanx/first metacarpal. Median…

Histology of StomachN

The stomach's histology reveals four main layers adapted for mechanical and chemical breakdown of food, starting with a mucosa of simple columnar epithelium rich in goblet cells secreting protective mucus…

Cutaneous Innervation to the Upper Limb Diagram

Cutaneous innervation of the upper limb includes dermatomes from C5-T1: axillary (regimental badge), musculocutaneous (lateral forearm), median (palm/thumb-index-middle), ulnar (little/ring), radial (dorsal hand). Overlap helps in nerve lesion mapping.

CT Scan Head Scanning Diagram

CT head scanning uses X-rays in axial slices, bone windows for skull fractures, soft tissue windows for hemorrhage/infarct/edema. Contrast enhances vessels/tumors; its fast for trauma/stroke evaluation.

The Stages of Walking Diagram

Stages of walking (gait cycle) include stance phase (heel strike, foot flat, midstance, heel off, toe off) and swing phase (acceleration, midswing, deceleration). Double support occurs in stance; single in…

Constiuent Parts of the Temporal Bone Diagram

This Constituent Parts of the Temporal Bone diagram pieces together the squamous, mastoid, petrous, and tympanic portions, highlighting landmarks like the zygomatic process, mastoid process, external acoustic meatus, styloid, and…

Ligaments of the Cervical Spine Diagram

Cervical spine ligaments: anterior/posterior longitudinal (along vertebral bodies), ligamentum flavum (laminae), interspinous/supraspinous (spinous processes), nuchal (posterior). They stabilize flexion/extension, limit excessive motion.

Organs

Anatomical Position of the Bulbourethral Glands Diagram

Bulbourethral glands (Cowpers) locate posterolateral to membranous urethra, below prostate, drain into bulbar urethra. They produce pre-ejaculatory mucus; Cowpers syringocele can obstruct.

Overview of the Dorsal Column Medial Lemniscal Pathway 1 Diagram

Medical

Overview of the Dorsal Column Medial Lemniscal Pathway Diagram

Dorsal column-medial lemniscus pathway carries fine touch, vibration, proprioception: ascends ipsilaterally in fasciculus gracilis/cuneatus, synapses in medulla nuclei, crosses as internal arcuate fibers to medial lemniscus, to thalamus, then cortex.

Medical

Medial and Lateral Pectoral Nerve Diagram

Medial pectoral nerve (C8-T1) pierces pectoralis minor to supply it and pectoralis major sternocostal head; lateral pectoral nerve (C5-C7) supplies clavicular head of pectoralis major. Both from brachial plexus.

Borders of the Triangular Interval Diagram

The Borders of the Triangular Interval diagram outlines this posterior arm space bounded by teres major superiorly, long head of triceps medially, shaft of humerus laterally, with radial nerve and…

First Layer of Plantar Muscles Diagram

First layer of plantar muscles: abductor hallucis (medial), flexor digitorum brevis (central), abductor digiti minimi (lateral). They arise from calcaneal tuberosity, support medial/longitudinal arch; medial/lateral plantar nerves supply.

Positive Trendlenburg Test Diagram

Positive Trendelenburg test: pelvis drops on unsupported side during single-leg stance due to weak gluteus medius/minimus (contralateral hip drop). Indicates superior gluteal nerve lesion, hip abductor weakness, or hip joint…
