For the occasion on which everyone already knows everyone else and the host wishes them to meet one or a few honored newcomers, then the `` open house '' system is advantageous because the honored guests are fixed connective points and the drifting guests make and break connections at the door.

Vertebrate brains are surrounded by a system of connective tissue membranes called meninges that separate the skull from the brain.

Target tissues may include muscles, tendons, ligaments, fascia, skin, joints, or other connective tissue, as well as lymphatic vessels, or organs of the gastrointestinal system.

Rheumatism is a non-specific term used to describe any painful disorder affecting the loco-motor system including joints, muscles, connective tissues, soft tissues around the joints and bones.

* Nasal muscles — The movements of the human nose are controlled by groups of facial and neck muscles that are set deep to the skin ; they are in four ( 4 ) functional groups that are interconnected by the nasal superficial aponeurosis — the superficial musculoaponeurotic system ( SMAS ) — which is a sheet of dense, fibrous, collagenous connective tissue that covers, invests, and forms the terminations of the muscles.

At the same time, the embryonic mesenchymal cells around the epithelial bud get secrecting factors activated by PTHrP, such as BMP4, can transform into a dense, mammary-specific mesenchyme, which later develop into connective tissue with fibrous threads, forming blood vessels and the lymph system.

The cells are capable of developing into connective tissue, such as bone, and cartilage, the lymphatic system, and the circulatory system.

One of the aims of this piece is to visualize complex dynamics, turning a condition of pure surveillance into an unpredictable connective system.

The mononuclear phagocyte system ( MPS ) is a part of the immune system that consists of the phagocytic cells located in reticular connective tissue.

Macrophages are diffusely scattered in the connective tissue and in liver ( Kupffer cells ), spleen and lymph nodes ( sinus histiocytes ), lungs ( alveolar macrophages ), and central nervous system ( microglia ).

This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments.

This defect leads to a multisystemic disorder of the connective tissue, muscles, CNS, and cardiovascular system.

For example, ICD-10 classifies " vasculitis limited to skin " with skin conditions ( under " L "), and " necrotizing vasculopathies " with musculoskeletal system and connective tissue conditions ( under " M ").

Proof-theoretic semantics is an approach to the semantics of logic that attempts to locate the meaning of propositions and logical connectives not in terms of interpretations, as in Tarskian approaches to semantics, but in the role that the proposition or logical connective plays within the system of inference.

From a dynamical systems perspective, the human movement system is a highly intricate network of co-dependent sub-systems ( e. g. respiratory, circulatory, nervous, skeletomuscular, perceptual ) that are composed of a large number of interacting components ( e. g. blood cells, oxygen molecules, muscle tissue, metabolic enzymes, connective tissue and bone ).

The mesoderm forms: skeletal muscle, the skeleton, the dermis of skin, connective tissue, the urogenital system, the heart, blood ( lymph cells ), the kidney, and the spleen.

The ectoderm forms: the central nervous system, the lens of the eye, cranial and sensory, the ganglia and nerves, pigment cells, head connective tissues, the epidermis, hair, and mammary glands.

A muscle biopsy can lead to the discovery of problems with a nervous system, connective tissue, vascular system, or musculoskeletal system.

Aberrant bone formation in patients with FOP occurs when injured connective tissue or muscle cells at the sites of injury or growth incorrectly express an enzyme for bone repair during apoptosis ( self-regulated cell death ), resulting in lymphocytes containing excess bone morphogenetic protein 4 ( BMP4 ) provided during the immune system response.

Mast cells originate from the bone marrow and are normally found throughout the connective tissue of the body as normal components of the immune system.

The upper, and in some cases the lower, mandibles are strengthened internally by a complex three-dimensional network of bony spicules ( or trabeculae ) seated in soft connective tissue and surrounded by the hard outer layers of the beak.

The lower or proximal portion of the spine has a rough surface that would have served as an anchoring point for the epaxial muscles of the back, and also has a network of connective tissues called Sharpey's fibers that indicate it was embedded within the body.

The cauda helicis ( tail of the helix ) is bound to the fibrofatty tissues of the earlobe by a network of connective tissue.

They describe a more realistic topology for the Internet – that is composed of LANs and ASs with a connective boundary – and attempt to put a single mark on inbound packets at the point of network ingress.

For example the standard glutamic acid ( glutamate ) and the non-standard gamma-amino acid gamma-amino-butyric acid ( GABA ) are respectively the brain's main excitatory and inhibitory neurotransmitters, hydroxyproline-a major component of the connective tissue collagen-is synthesised from proline, the standard amino acid glycine is used to synthesise porphyrins used in red blood cells, and the non-standard carnitine is used in lipid transport.

These modifications are often essential for the function or regulation of a protein ; for example, the carboxylation of glutamate allows for better binding of calcium cations, and the hydroxylation of proline is critical for maintaining connective tissues.

It is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the world ocean.

In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen.

Bone tissue is a type of dense connective tissue.

Intramembranous ossification mainly occurs during formation of the flat bones of the skull but also the mandible, maxilla, and clavicles ; the bone is formed from connective tissue such as mesenchyme tissue rather than from cartilage.

In a TRAM procedure, a portion of the abdomen tissue group, including skin, adipose tissues, minor muscles and connective tissues, is taken from the patient's abdomen and transplanted onto the breast site.

In addition to the milk glands, the breast also is composed of connective tissues ( collagen, elastin ), white fat, and the suspensory Cooper's ligaments.

The inframammary fold, where the lower portion of the breast meets the chest, is an anatomic feature created by the adherence of the breast skin and the underlying connective tissues of the chest ; the IMF is the lower-most extent of the anatomic breast.

Collagen () is a group of naturally occurring proteins found in animals, especially in the flesh and connective tissues of vertebrates.

It is the main component of connective tissue, and is the most abundant protein in mammals, making up about 25 % to 35 % of the whole-body protein content.

Paradoxically, achieving this connective human quality has also moved his buildings away from the abstract imageability valued in contemporary architecture, and this is one reason why his buildings are under-appreciated at present.

In logic and mathematics, a two-place logical connective or, is a logical disjunction, also known as inclusive disjunction or alternation, that results in true whenever one or more of its operands are true.

Gelatin is a mixture of peptides and proteins produced by partial hydrolysis of collagen extracted from the skin, boiled crushed horn, hoof and bones, connective tissues, organs and some intestines of animals such as domesticated cattle, chicken, horses, and pigs.

In some vertebrates, haematopoiesis can occur wherever there is a loose stroma of connective tissue and slow blood supply, such as the gut, spleen, kidney or ovaries.

In logic and related fields such as mathematics and philosophy, if and only if ( shortened iff ) is a biconditional logical connective between statements.

In that it is biconditional, the connective can be likened to the standard material conditional (" only if ", equal to " if ... then ") combined with its reverse (" if "); hence the name.

It is controversial whether the connective thus defined is properly rendered by the English " if and only if ", with its pre-existing meaning.
