![]() ![]() Identify the regions of the ventricular system and associate each region with a specific portion of the cranial region of the neural tube. Rhombencephalon Mesencephalon I r1 r2 r3 r4 r5 r6 r7 Cranial nerves Mesencephalic flexure Cervical flexure Prosencephalon Optic Prosencephalon sulcus A 28. ventral surface of the mesencephalic flexure expressed Ptx3. pontine flexure a flexure of the hindbrain in the embryo. Identify the five secondary vesicles of the cranial portion of the neural tube, and name which region of the mature brain these vesicles develop into. ABSTRACT The mesencephalic dopaminergic (mesDA). Published on Splenic flexure syndrome occurs as a result of muscle spasms and abdominal distention leading to pain and discomfort in the upper abdomen. mesencephalic flexure a bend in the neural tube of the embryo at the level of the mesencephalon, or mid-brain. Identify the three primary vesicles of the cranial portion of the neural tube. ![]() ![]() The cervical flexure makes a 90 bend between hind-brain and spinal cord causing the brain. By the end of the module, learners will be able to:ĭraw or describe the three-dimensional shape of the neural tube as it appears after neurulation.ĭraw or describe the following structures within the neural tube: neural canal, alar plates, and basal plates. Cephalic (mesencephalic) flexure, in the region of midbrain. ![]()
