| 90 | The endometrium through the menstrual cycleThe lining of the uterus at three points in the menstrual cycle, side by side on the same muscle: at menstruation, the functional layer breaking away in blood; in the proliferative phase, under oestrogen, straight glands in a growing stroma; in the secretory phase, under progesterone, coiled, saw-toothed glands full of secretion, a swollen stroma and coiled spiral arteries. The basal layer, which is never shed, is the same in all three. | Reproductive | 20 | 7 | 2 | Get3DMed | ||
| 91 | The gut wall, region by regionBlocks of the gut wall side by side, each cut through every layer: the oesophagus, with its thick squamous lining, submucosal glands and skeletal-to-smooth muscle; the gastro-oesophageal junction, where the squamous lining meets the stomach’s columnar mucosa at the Z-line; the body of the stomach, its pits and glands drawn cell by cell (surface mucous, mucous neck, parietal, chief and enteroendocrine cells) with a ruga and three muscle layers; and the colon, with straight crypts full of goblet cells and a taenia coli. The small intestine is the gut wall model. | Digestive | 27 | 7 | 4 | Get3DMed | ||
| 92 | The newborn skullThe skull of a term newborn, life size: the frontal bone in two halves, the parietal, occipital, temporal and sphenoid bones over a small face, joined by the metopic, coronal, sagittal, lambdoid and squamous sutures, with the anterior, posterior, sphenoidal and mastoid fontanelles, and the bones overlapping as in moulding at birth. | Skeletal, Joints and ligaments | 35 | 9 | 2 | Z-Anatomy | ||
| 93 | Brain and spinal cord under the microscopeBlocks of the central nervous system, each cut to show its layers: the six layers of the cerebral cortex with pyramidal, Betz, granule and fusiform cells, motor beside sensory cortex; the cerebellar cortex with its molecular, Purkinje cell and granular layers, Purkinje cell fans, parallel and climbing fibres; the cervical spinal cord cut across, with its grey horns, substantia gelatinosa, central canal, the dorsal columns, corticospinal, spinothalamic and spinocerebellar tracts, rootlets and meninges; and a capillary of the blood-brain barrier with tight junctions, a pericyte and astrocyte end-feet. | Nervous | 50 | 10 | 8 | Get3DMed |
