Ocellus
Definition:
(n.) A little eye; a minute simple eye found in many invertebrates.
(n.) An eyelike spot of color, as those on the tail of the peacock.
Example Sentences:
(1) Each ocellus has a cuticular lens located on the distal end of a cuticular cone which encapsulates the receptor cells.
(2) It appears, therefore, that the graded receptor potential, which survives the application of tetrodotoxin, is responsible for mediating synaptic transmission in the ocellus.
(3) The receptory area of the ocellus terminates in a tapetum which contains granules, soluble in alcohol.
(4) A third type comes from the median ocellus and can be traced into the cervical connectives.
(5) This idea and alternatives have been tested on the barnacle lateral ocellus, a simple eye with only three photoreceptors, each with its own axon about 1 cm long.2.
(6) Membrane potential changes following illumination of a photoreceptor cell in the lateral ocellus of a barnacle (Balanus eburneus) were studied by means of intracellular recording and polarization techniques.
(7) The decay of the depolarizing and hyperpolarizing components of the visual signal was studied by recording intracellularly from single receptor axons of the median ocellus of the giant barnacle.2.
(8) Each ocellus has about 80 retinula cells whose axons project to corresponding ganglia from which 4 giant afferent interneurons (per ganglion) project to the brain.
(9) The visual pigment of each ocellus of mosquitoes reared in darkness was characterized by microspectrophotometry, and found to be the same.
(10) However, the two bilaterally positioned cells destined to become the pigment cells in the first step are still equipotent at this stage in that they can give rise to either the ocellus or otolith.
(11) Anatomically, the sensory cells of the dorsal ocellus of Tenodera were determined histologically to be grouped into two distinct regions, each group making its own separate contribution to the ocellar nerve.
(12) In the absence of this interaction, melanocyte specification proceeds along the dominant pathway that results in the differentiation of an ocellus.
(13) Five cells are accessory cells of the sensory structures: three lens cells and a pigment-cup cell in the ocellus, and a single pigment cell in the otolith.
