Brachyglottis is a genus of flowering plants in the family Asteraceae.The genus was erected on November 29, 1775, [2] [3] by Johann Reinhold Forster and Georg Forster.The name was derived from the Greek brachus ("short") [4] and glottis ("the vocal apparatus of the larynx" [5]) a reference to the size of the ray florets.
The glottis (pl.: glottises or glottides) is the opening between the vocal folds [1] (the rima glottidis). [2] The glottis is crucial in producing sound from the vocal folds. Etymology
Glottiphyllum is a genus of about 57 species of succulent subtropical plants of the family Aizoaceae.It is closely related to the Gibbaeum and Faucaria genera. The name comes from ancient Greek γλωττίς glottis "tongue" and φύλλον phyllon "leaf".
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
Plant structures or organs fulfil specific functions, and those functions determine the structures that perform them. Among terrestrial (land) plants, the vascular and non-vascular plants (Bryophytes) evolved independently in terms of their adaptation to terrestrial life and are treated separately here (see Bryophytes ).
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 rima glottidis is the narrowest part of larynx. It is longer (~23 mm) in males than in females (17–18 mm). [1]The rima glottidis is an aperture between the two true vocal cords anteriorly, and the bases and vocal process of the two arytenoid cartilages posteriorly.
The length of the vocal fold at birth is approximately six to eight millimeters and grows to its adult length of eight to sixteen millimeters by adolescence. The infant vocal fold is half membranous or anterior glottis, and half cartilaginous or posterior glottis. The adult fold is approximately three-fifths membranous and two-fifths cartilaginous.
