What's the difference between antler and surroyal?

Antler

Definition:

(n.) The entire horn, or any branch of the horn, of a cervine animal, as of a stag.

Example Sentences:

(1) We conclude from this study that there is little or no seasonal photoperiodic entrainment of the antler and testicular cycles of males in this population of axis deer.
(2) Thyroxine (T4), triiodothyronine (T3), and alkaline phosphatase (AP) were assayed monthly in white-tailed deer plasma obtained from the antler (A), jugular (J), and the saphenous (S) veins during the period of antler growth and the period of mineralization.
(3) From the polymorphic loci examined, certain alleles at Idh-2, Me-1 and Acp-1 showed significant associations with a special development of body and antler characters selected for by hunters.
(4) The major aims of this study were to identify and localize by immunohistochemical techniques the type of innervation present, and to find out whether nerve fibres could exhibit growth rates comparable to those of antler.
(5) Detailed information obtained from 4 stags indicated that there was a fixed relationship between stage of the antler cycle and testis diameter; minimum testis diameter occurred 1-2 months after antler casting whereas maximum testis diameter occurred when stags were in hard antler.
(6) Proteinaceous extracts of deer and antelope antlers and bovine and rhinoceros horn were prepared by solubilizing 10 mg of horn sample in 200 microL of a solution containing 12M urea, 74mM Trizma base, and 78mM dithiothreitol (DTT).
(7) Unlike human bone, reindeer antler always shows a large post-yield strain, and it is possible to distinguish pre-yield and post-yield behaviour.
(8) Four adult male fallow deer were investigated for 1-4 consecutive years to study the relationships between annual changes in testis volume, sperm quality and antler status.
(9) Artificial extension of day-length in adult male white-tailed deer during the autumn induced: (a) premature casting of antlers, early onset of the new antler growth and out of season mineralization, (b) early elevation of plasma levels of prolactin, LH, FSH, testosterone and alkaline phosphatase and (c) out of season hair molt.
(10) Under both sets of conditions, antlers were repeatedly shed and replaced, usually in synchrony with every other time the day lengths were changed.
(11) An anti-inflammatory compound was purified and isolated from pilose antler of Cervus nippon Temminck by dialysis, gel filtration and ion-exchange chromatography techniques.
(12) Cleaning of velvet and casting of antlers following castration were unaffected by denervation.
(13) The composition of the antlers did not vary significantly between penned and grazing stags or with age.
(14) The data indicate that: 1) similarly to other mammals, deer exhibit peak levels of M during the dark phase; 2) 5 mg of M given orally caused a rapid elevation of M levels in blood followed by a depression of the normally present night-time peak; and 3) midscotophase levels of M exhibit very pronounced seasonal fluctuations which might be related to yearly cycles, such as the reproduction, hair molt, and antler growth.
(15) Electrodes were connected to a high input impediance microvoltmeter, and potentials on the surface of antlers of mature deer were measured during the antler growth cycle.
(16) Years ago, when I was studying anthropology at university, one of my female professors held up a photograph of an antler bone with 28 markings on it.
(17) Both bucks also had patchy areas of alopecia around the base of antlers.
(18) The study, spread over six consecutive years, reveals the following seasonal T changes: Minimum concentrations in November or December, around antler casting and at early antler growing phase; increasing levels in the course of late antler development (mineralization) with relatively high values around velvet shedding; peak levels occurring during onset of rutting period followed by a sharp decrease after the rut; and distinct and oscillating T peaks during late winter and spring.
(19) Biopsy samples of the main beams and tines were obtained from the antlers of mature Rocky Mountain mule deer (Odocoileus hemionus hemionus) during the rapid phase of the antler grow-th cycle.
(20) These antlers shed their velvet in the fall, and in succeeding years are replaced by larger outgrowths not exceeding 7 cm in length.
