The rhombic lip can be divided into eight structural units based on rhombomeres 1-8 (r1-r8), which can be recognized at early stages of hindbrain development. [2] Producing granule cells and five brainstem nuclei, the rhombic lip plays an important role in developing a complex cerebellar neural system. [3] Rhombic lips
The physiological unity of plants and animals: a lecture delivered before the Sunday Lecture Society, on Sunday afternoon, 30th January, 1881 by Boulger, G.S. Items portrayed in this file depicts
UBCs function to amplify inputs from the vestibular ganglia and nuclei by spreading and prolonging excitation within the granular layer. [ 2 ] [ 7 ] They receive glutamatergic inputs on its dendritic brush from a single mossy fibre terminal in the form of a giant glutamatergic synapse and make glutamatergic synapses with granule cells and other ...
There are three physiological developments that must occur in order for this to take place: firstly, the plant must pass from sexual immaturity into a sexually mature state (i.e. a transition towards flowering); secondly, the transformation of the apical meristem's function from a vegetative meristem into a floral meristem or inflorescence; and ...
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
The alar plate (or alar lamina) is a neural structure in the embryonic nervous system, part of the dorsal side of the neural tube, that involves the communication of general somatic and general visceral sensory impulses.
Substances may be excreted to the surface of the plant or into intercellular cavities or canals. Some of the many substances contained in the secretions are not further utilized by the plant (resins, rubber, tannins, and various crystals), while others take part in the functions of the plant (enzymes and hormones).
Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1]
