In the developing nervous system, the basal plate is the region of the neural tube ventral to the sulcus limitans. It extends from the rostral mesencephalon to the end of the spinal cord and contains primarily motor neurons, whereas neurons found in the alar plate are primarily associated with sensory

Oct 26, 2023 · The maternal surface of the placenta, or basal plate, is an artificial surface, which emerges from the separation of the placenta from the uterine wall during delivery.

Basal plate may refer to: Basal plate (neural tube), the region of the neural tube ventral to the sulcus limitans; Basal plate (placenta), between this plate and the uterine muscular fibres are the stratum spongiosum and the boundary layer; The base of a plant's bulb; The pedal disc, in anatomy of the sea anemone, the surface opposite to the mouth

The basal plate is closest to the ventral midline of the neural tube, which will become the anterior face of the spinal cord and gives rise to motor neurons. The alar plate is on the dorsal side of the neural tube and gives rise to neurons that will receive sensory input from the periphery.

Feb 24, 2023 · The basal plate is the compact, fleshy stem found in bulbs. It is the location where the new organs form on the bulb. Meristems that form on the basal plate include those for vegetative and flowering stem, new buds that will form offsets, and the root system that arises as adventitious roots.

5 days ago · The meaning of BASAL PLATE is an underlying structure. the part of the decidua of a placental mammal that is intimately fused with the placenta

In the developing nervous system, the basal plate is the region of the neural tube ventral to the sulcus limitans. It extends from the rostral mesencephalon to the end of the spinal cord and contains primarily motor neurons, whereas neurons found in the alar plate are primarily associated with sensory

Aug 20, 2024 · The basal plate also further develops general motor efferents (GME) innervating somatic muscles, special motor efferents (SME) innervating branchial arch-derived muscles, and visceral motor efferents (VME) innervating autonomic (respiratory, cardiac, and gastrointestinal system) muscles.

Summarizing again: as indicated by Wilhelm His, the entire brainstem (i. e. the rhombencephalon plus the mesencephalon) can be divided into a primarily motor basal plate and a primarily sensory alar plate. A sulcus limitans, marking the boundary of the basal and alar plates on the ventricular side, is confined to the rhombencephalon.

The term basal plate refers to an embryologic structure that develops as a result of the proliferation of ectodermal cells in the mantle layer of the portion the neural tube that is developing into the spinal cord.
