Selaginella canaliculata Selaginella selaginoides Selaginella willdenowii is known for its iridescent colours. There are about 750 known species of Selaginella. [21] They show a wide range of characters; the genus is overdue for a revision which might include subdivision into several genera. [citation needed] Species of spikemoss include:
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
Selaginella moellendorffii is a lycophyte that is an important model organism, especially in comparative genomics. S. moellendorffii is a member of an ancient vascular plant lineage that first appeared in the fossil record some 400 million years ago. They would later form a dominant part of the world's flora during the Carboniferous period.
They are defined by two synapomorphies: lateral rather than terminal sporangia (often kidney-shaped or reniform), and exarch protosteles, in which the protoxylem is outside the metaxylem rather than vice versa.
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
Selaginella stellata, also recognized by its common name, starry spikemoss [1] or starry spike-moss, is a species of spikemoss of the family Selaginellaceae. It is a type of lycopod that grows naturally in Mexico and Central American countries like Guatemala and Belize [ 2 ] and can also be found in the state of Hawaii .
The exact roles of the specific neurons making up the mushroom bodies are still unclear. However, these structures are studied extensively because much is known about their genetic make-up. There are three specific classes of neurons that make up the mushroom body lobes: α/β, α’/β’, and γ neurons, which all have distinct gene expression.
Selaginella selaginoides is a non-flowering plant of the spikemoss genus Selaginella with a wide distribution around the Northern Hemisphere. It resembles a moss in appearance but is a vascular plant belonging to the division Lycopodiophyta .
