What's the difference between capitulum and hypostome?
Capitulum
Definition:
(n.) A thick head of flowers on a very short axis, as a clover top, or a dandelion; a composite flower. A capitulum may be either globular or flat.
(n.) A knoblike protuberance of any part, esp. at the end of a bone or cartilage. [See Illust. of Artiodactyla.]

(14) While the X-ray from the date of accident only showed a tiny osseus avulsion fracture out of the base of the proximal phalanx II--in spite of the immediately taken accurate therapeutical provisions (by fixation with plaster and later on paviment dressing)--there took place a massive epiphyseonecrosis of the capitulum II within only three months.--The etiology of the necrosis--direct trauma of the nutritive arteries passing through the collateral ligaments--is discussed.
(15) The commonly affected sites are the femoral head, the femoral condyles, the humeral head, the talus and the capitulum.
(16) Straining is triggered by a connective-tissue and bony protuberance produced by mechanical irritation on the lateral capitulum mandibulae.
(17) The results refer to the movement of the discus and the capitulum mandibulae and to the effects of the musculus temporalis and of the facies articularis ossis temporalis.
(18) In all volunteers by the electric stimulation of the ulnar nerve in the region of the wrist and the peroneal nerve in the region of the fibular capitulum there have been measured the F wave latency, distal latency of M responses and the conduction time of the peripheral motor neuron has been calculated.
(19) In some cases pronounced wear of the metatarsal capitulum was seen, with synovitis of varying degrees of clinical severity.
(20) The diagnostic yield of different electrophysiological criteria was examined to establish whether a peroneal palsy was due to compression of the nerve in the region of the capitulum fibulae.
Hypostome
Definition:
(n.) Alt. of Hypostoma
Example Sentences:
(1) The external surface of the hypostome possesses cnidocils, possibly sensory hairs, and small spiny protrusions surrounding the mouth; the internal surface has cylindrical microvilli, free flagella and adherent flagella.
(2) Additional observations on some fine structures of Demodex folliculorum under SEM were presented in this paper, including supracoxal spines, hypostome, palpal claws, male and female podosomal setae, leg claw-basal spur, femoral spur, etc.
(3) Nile-blue-stained cells from hypostome or peduncle did not form specific structures in the reconstructed polyp, but were distributed throughout the animal.
(4) A population of sensory nerve cells localized in the head (hypostome and tentacles) is identified by the binding of antibody JD1.
(5) The second was an antiserum against the peptide Arg-Phe-amide (RFamide), which in the head of hydra is specific to the sensory cells of the hypostomal apex and the ganglion cells of the lower hypostome and tentacles.
(6) The normal morphology of the hypostome and mouth of hydra were examined by transmission electron microscopy with conventional thin sections and freeze-fracture replicas.
(7) The same midpiece tissue differentiated to a basal disc when grafted near the host hypostome, and to a small hypostome with tentacles when grafted near the host basal disc.
(8) Myonemes of the hypostome are small in diameter, have gap and intermediate-type cell junctions within each epithelial layer and are associated with the opposite epithelial layer by transmesogleal processes and gap junctions.
(9) It is a distinct neuronal complex consisting of a thick nerve bundle running circumferentially at the border between the hypostome and tentacle zone.
