What's the difference between acanthus and canthus?
Acanthus
Definition:
(n.) A genus of herbaceous prickly plants, found in the south of Europe, Asia Minor, and India; bear's-breech.
(n.) An ornament resembling the foliage or leaves of the acanthus (Acanthus spinosus); -- used in the capitals of the Corinthian and Composite orders.
Example Sentences:
(1) In general P. megalurus rediae resemble more closely rediae of the philophthalmid Parorchis acanthus than they do those of P. gralli.
(2) Extrinsic enzymes were not needed for C. tilapiae excystation but were an absolute necessity for P. acanthus excystation.
(3) Excystment of metacercariae of Parorchis acanthus, Posthodiplostomoides leonensis, Posthodiplostomum sp.
(4) n. (Philophthalmidae) from the Bursa Fabricii and lower intestine; and the following previously known species, all representing new host records: Maritrema arenaria and Probolocorphye glandulosa (Microphallidae); Lyperosomum oswaldoi and L. sinuosum (Dicrocoeliidae); Cyclocoelum obscurum (Cyclocoelidae); Himasthla rhigedana (Echinostomatidae); and Parorchis acanthus (Philophthalmidae).
(5) Excystation of metacercariae of Parorchis acanthus, Posthodiplostomum nanum, Posthodiplostomum sp., Posthodiplostomoides leonensis and Clinostomum tilapiae in mammalian saline at 39 degrees C was similar to their excystation in mouse peritoneal cavity.
(6) But if you want leafiness, there are some species adapted to dry shade: acanthus, or native ferns like the hart's tongue will provide foliage without robbing water supplies.
(7) The stages of C. michiganensis resembled those of Parorchis acanthus, a philophthalmid also infecting C. californica, except for differences in the epidermal plate count of their miracidia and in their cercarial stage which was larger in P. acanthus and had a spinuous tegument with a collar of spines.
Canthus
Definition:
(n.) The corner where the upper and under eyelids meet on each side of the eye.
Example Sentences:
(1) The operative approach is through an incision above the medial canthus.
(2) All recurrences of primary lesions post-Mohs surgery were located in the medial canthus.
(3) Large defects after Mohs' surgery for these lesions may involve the nose, cheek, forehead, and other parts of the face as well as the eyelids, medial canthus, and lacrimal drainage system.
(4) To quantify the distribution, the distance from the bony lateral canthus (LC) to the points where the temporal branches crossed two standard lines, (L1 and L2) were measured.
(5) The tarsal strips are sutured to periosteum at the lateral orbital wall, adjusting the height and tension of the lateral canthus.
(6) The results, as manifest by appearance of the lateral canthus and position of the eyelid in apposition to the globe, were graded as excellent in all patients and orbits.
(7) The apparatus described here consists of a replaceable plastic tank under mechanical pressure attached to capillary tubing which is kept in contact with the inner canthus of the eye.
(8) In 7 patients, an eyelid suspension was performed with PTFE by Arion's technique, but by replacing the classical silicon thread by E-PTFE and transposing the medial part of the temporalis muscle on the external canthus, and fixing the lateral end of the sling to the muscle.
(9) The pinch technique has also been found useful when upper and lower blepharoplasties are joined laterally to elevate the lateral canthus and eliminate "crow's feet."
(10) The lateral canthus and lower eyelid are elevated with the tarsal tuck, which reduces the amount of skin removal required and avoids the "round eye" appearance.
(11) The examination of 250 cases of onchocerciasis from the Sudan-savanna of northern Cameroon showed a strong association between microfilarial invasion of the eye and microfilarial skin concentrations at the outer canthus.
(12) The alterations include the following: (1) the excision of a Burow's triangle superior edge of the defect toward the inner canthus; (2) the use of a periosteal or suspension suture to minimize tenting across the concave junction of the nose and cheek; (3) wide undermining of the skin surrounding the defect to create a stabilizing platelike scar; (4) significant thinning of the donor flap; and (5) adjust the size of the flap to recreate the original preincisional skin tension on the flap after suturing.
(13) The scared look caused by the overcorrection of the frontal area and mobilization of the lateral canthus of the eye and mouth are frequent complications or failures in rhytidectomy.
(14) After localization of the tumor the inner canthus in particular should be kept under observation for recurrences.
(15) The inner canthus electrode was considered preferable for noncorneal recording because it was less affected by other time-locked activity; it correlated well with the corneal ERG and can be used in conjunction with the electro-oculogram.
(16) The lateral tarsal strip procedure has the combined effect of increasing horizontal lid tension and adjusting the level of the lateral canthus.
(17) Limberg's "rhomboid flap" is a technique which has been modified especially to suit the particular anatomy of the medial canthus.
(18) The most frequent sites were the nose (33.8% of BC), the inner canthus (12.7% of BC), the lower lip (23.8% of EC) and the ear (15.6% of EC).
(19) The distance between the point which is located 10 mm posterior to the medial canthus and the anterior cranial fossa floor was measured.
(20) Surgical management of carcinomas at the inner canthus is based on three criteria which are listed in a descending order of importance: tumor resectability with adequate margins, preservation of vision, and acceptable cosmetic result.
