例句 | Spongy bone is made of tiny plates called trabeculae.

Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 8 "Dubner" to "Dyeing" 2010-12-26T03:00:17.840Z Spongy bone tissue is composed of trabeculae and forms the inner part of all bones. Biology for AP Courses 2022-06-09T00:00:00Z Beneath the arachnoid is a thin, filamentous mesh called the arachnoid trabeculae, which looks like a spider web, giving this layer its name. Anatomy and Physiology 2013-06-19T00:00:00Z In others the peripheral ends of the septa are united only by bars or trabeculae, so that the theca is perforate, and in many such perforate corals the septa themselves are pierced by numerous perforations. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 2 "Anjar" to "Apollo" Sperm sacs generally limited to one or two segments with interior subdivided by trabeculae. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 7 "Cerargyrite" to "Charing Cross" The medial liver trabecula into which the enteron was seen to open, in the preceding figure, now opens ventrally to the yolk-sac as the anterior intestinal portal. Development of the Digestive Canal of the American Alligator Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates. Biology for AP Courses 2022-06-09T00:00:00Z The trabeculae are found in the subarachnoid space, which is filled with circulating CSF. Anatomy and Physiology 2013-06-19T00:00:00Z The aporose corals, too, have a practically identical structure, their compactness being due to the union of the trabeculae throughout their entire lengths instead of at intervals, as in the Perforata. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 2 "Anjar" to "Apollo" Sperm sacs generally occupying a good many segments and with simple interior undivided by a network of trabeculae. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 7 "Cerargyrite" to "Charing Cross" A few liver trabeculae are to be seen on either side of the portal, but they show no lumena, and may be traced through only a few sections. Development of the Digestive Canal of the American Alligator With certain differences of form these elements-- the trabeculae, the parachordals, and the otic capsules, are also the first formed structures of the mammalian cranium. Text Book of Biology, Part 1: Vertebrata The trabeculae may appear to be a random network, but each trabecula forms along lines of stress to provide strength to the bone. Anatomy and Physiology 2013-06-19T00:00:00Z Further, the trabeculae may be evenly spaced throughout the septum, or may be grouped together, and this feature is probably of value in estimating the affinities of corals. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 2 "Anjar" to "Apollo" The heart possesses only one pair of fissures, and has no muscles traversing its interior like trabeculae, whilst in other Zoeae two pairs of fissures and an interior apparatus of trabeculae are always distinctly recognisable. Facts and Arguments for Darwin This cavity is a part of the system of hollow liver trabeculae seen as a group of irregular masses of cells ventrad to the enteron at the opening of the anterior intestinal portal. Development of the Digestive Canal of the American Alligator Cancellous bone looks like a sponge under the microscope and contains empty spaces between trabeculae, or arches of bone proper. Anatomy and Physiology 2013-06-19T00:00:00Z In addition, the spaces in some spongy bones contain red marrow, protected by the trabeculae, where hematopoiesis occurs. Anatomy and Physiology 2013-06-19T00:00:00Z The trabeculae are united together by these thickened internodes, and the result is a fenestrated septum, which in older septa may become solid and aporose by continual deposit of calcite in the fenestrae. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 2 "Anjar" to "Apollo" The heart acquires new fissures, and interior muscular trabeculae. Facts and Arguments for Darwin The trabeculae and lobules, including the darkly staining cortex and the lighter staining medulla of each lobule, are clearly visible in the light micrograph of the thymus of a newborn. Anatomy and Physiology 2013-06-19T00:00:00Z The connective tissue capsule further divides the thymus into lobules via extensions called trabeculae. Anatomy and Physiology 2013-06-19T00:00:00Z Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae. Anatomy and Physiology 2013-06-19T00:00:00Z The septa of modern perforate corals are shown to have a structure nearly identical with that of the secondary forms, but the trabeculae and their nodes are only apparent on microscopical examination. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 2 "Anjar" to "Apollo" Like the thymus, the bean- shaped lymph nodes are surrounded by a tough capsule of connective tissue and are separated into compartments by trabeculae, the extensions of the capsule. Anatomy and Physiology 2013-06-19T00:00:00Z In addition to the structure provided by the capsule and trabeculae, the structural support of the lymph node is provided by a series of reticular fibers laid down by fibroblasts. Anatomy and Physiology 2013-06-19T00:00:00Z Each node of a trabecula may be simple, i.e. have only one centre of calcification, or may be compound.
