6 天之前 · The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variants—bone, ligaments, tendons, cartilage, and adipose (fat) tissue.

hyaline cartilage, type of connective tissue, glossy pearl-gray or blue-white in appearance and resilient, found on surfaces of joints and in the cartilage making up the fetal skeleton.

Fibroblast, the principal active cell of connective tissue. Fibroblasts are large flat spindle-shaped cells with processes that extend out from the ends of the cell body. Fibroblasts produce tropocollagen, the forerunner of collagen, and ground substance. Learn more about the function and appearance of fibroblasts.

2024年12月3日 · At the light-microscope level, the fibres vary in diameter and often branch and reunite to form extensive networks in loose connective tissue. When present in high concentration, they impart a yellow colour to the tissue.

2025年1月22日 · adipose tissue, connective tissue consisting mainly of fat cells (adipose cells, or adipocytes), specialized to synthesize and contain large globules of fat, within a structural network of fibres.

fibrocartilage, type of connective tissue that provides structural support for the musculoskeletal system. Fibrocartilage is very strong. It is found predominantly in the intervertebral disks of the spine and at the insertions of ligaments and tendons.

2024年12月3日 · connective tissue; fibrocyte Electron micrograph of a small area of dense fibrous connective tissue, illustrating the intimate association of cells and fibres. In the centre is a portion of a fibrocyte, and on either side are two collagen fibres.

Elastic fibre, any of the yellowish branching fibres composed primarily of the protein elastin, frequently arranged in plates or perforated membranes, as in the walls of the large arteries. Unlike collagenous fibres, they show no orderly fibrous subunits under …

The most diffuse lymphoid tissue is found in the loose connective-tissue spaces beneath most wet epithelial membranes, such as those that line the gastrointestinal tract and the respiratory system. In these spaces many cells of the lymphatic system wander and become exposed to invading microorganisms and foreign material.

In connective tissue: Migrating cells …from the blood is the monocyte, a mononuclear cell larger than the lymphocyte and with different potentialities. These migratory cells can divide and, when appropriately stimulated, can transform into highly phagocytic macrophages.
