MT30-Histology Art AB 3 years, 11 months agoAreolar connective tissue is a kind of connective tissue that connects and surrounds the human body’s organs. This type of tissue has two important functions: it nourishes the cells and acts as a cushion to protect the organs from external forces-
Areolar tissue is found under the dermis layer and beneath the epithelial tissue of all bodily systems having external openings.

Because of its location in the excretory system, notably the ureters and urinary bladder, this tissue serves as an unusually efficient permeability barrier, impervious to water and most small molecules.
-
Because it is nearly totally found in the bladder, ureters, and urethra, it is also known as urothelium.

MT30-Histology Art AB 3 years, 11 months agoFibrocartilage is a stiff, strong tissue found mostly in intervertebral disks as well as at ligament and tendon insertions; it is like other fibrous tissues but contains cartilage ground material and chondrocytes.-
Fibrocartilage is the tough substance found in intervertebral discs, intraarticular cartilages in the knee, wrist, and temporo-mandibular joints, and articular cartilage in the temporo-mandibular and clavicle-sternum joints.

MT30-Histology Art AB 3 years, 11 months agoCollagenous Connective Tissue
While flexible, collagen strands have great tensile strength, resist stretching, and give the characteristic resilience and strength of ligaments and tendons. Even when the body is moving, these fibers maintain connective tissues together-
Collagen fibers are structural components in vertebrate tissues that transfer stresses, store energy, and dissipate energy. Collagen fibers have a hierarchical structure composed of collagen molecules, microfibrils, fibrils, fibers, and fascicles, and they restrict tendon and other load-bearing tissue deformation
-
Collagenous fibers are formed of type I, II, or III collagen and are present in all forms of connective tissue. The ratio of collagen fibers to ground material distinguishes two forms of collagenous connective tissue
-
The most frequent form of collagenous connective tissue is loose connective tissue (areolar connective tissue). It occurs in tiny, elongated bundles separated by ground material areas.
-
In thick connective tissue with minimal ground material, collagen fibers are plentiful. If the densely packed bundles of fibers are aligned in one direction, it is called regular; if they are oriented in several directions, it is called irregular
-
The dermis is an example of irregular dense connective tissue, whereas tendons are examples of regular dense connective tissue.

MT30-Histology Art AB 3 years, 11 months agoHyaline cartilage is the glassy (hyaline) and transparent cartilage found on many joint surfaces. The ribs, nose, larynx, and trachea all contain hyaline cartilage. It…-
Externally, hyaline cartilage is protected by the perichondrium, also known as the synovial membrane, when it runs along articulating surfaces. Capillaries in this membrane give nourishment to the cartilage through diffusion
-
The major components of hyaline cartilage matrix are type II collagen and chondroitin sulphate, which are also found in elastic cartilage.
-
Hyaline cartilage can be found on the sternal ends of the ribs, in the larynx, trachea, and bronchi, and on the articulating surfaces of bones. It gives the structures a solid but flexible aspect. Collagen fibers provide such structures and joints strength, but they also limit mobility and flexibility.

Three or more processes are associated with the cell bodies of multipolar neurons. The axon transports electrical impulses (action potentials)…-
Multipolar neurons have dendrites that allow them to take impulses from many neurons. Dendrites communicate across the neuron via an electrical signal that travels down the axon. Motor neurons are the most common type of nerve cell body plan: they are multipolar, with one axon and several dendrites.

MT30-Histology Art AB 3 years, 11 months agoCardiac muscle, also known as myocardium, is one of three primary muscle groups found solely in the heart in vertebrates. Cardiac muscle, like skeletal muscle, has contractile units known as sarcomeres, which distinguishes it from smooth muscle, the third muscle type.-
Cardiac muscle differs from skeletal muscle in that it contracts on a regular basis and lacks voluntary control. The sinoatrial node, which serves as the heart’s pacemaker, regulates the rhythmic contraction of cardiac muscle
-
The heart is mostly composed of cardiac muscle cells (or myocardium). Two of its most noticeable characteristics are the contractility of the heart, which serves as the foundation for its pumping function, and the rhythmicity of the contraction
-
To meet the metabolic demands of peripheral tissues such as skeletal muscles, kidneys, brain, skin, liver, heart, and gastrointestinal tract, the cardiac output (the amount of blood pumped by the heart per minute) fluctuates.
-
Cardiac muscle cells form a highly branched cellular network in the heart. They are composed of myocardial tissue layers that wrap around the chambers of the heart and are linked end to end by intercalated disks

Skeletal muscle tissue cells are voluntary, striated, non-branched, and multinucleated. Skeletal muscle tissue is the only type of muscle tissue that is directly controlled by the cerebral cortex of the brain, giving it the label of voluntary muscle
-
All conscious bodily motions, including limb movement, face expressions, eye movements, and swallowing, are controlled by skeletal muscle tissue. Skeletal muscle contractions provide most of the body’s heat because of cellular metabolism.
-
Skeletal muscle cells differ from other muscle tissues because of their structure. Skeletal muscle cells are generated throughout fetal development by the union of numerous smaller cells, resulting in long, straight muscle fibers with many nuclei
-
When studied under a microscope, skeletal muscle cells exhibit a striped, or striated, pattern of bright and dark areas. These stripes are caused by the orderly…
