Skeksis

Skeletá

Skeletá is Ghost's sixth studio album, released April 25, 2025 on Loma Vista, featuring Papa V Perpetua; it gave the band its first US Billboard 200 No. 1.

Skeletal animation

Skeletal animation, also called skinned animation, is a technique for animating a 3D mesh by attaching it to a skeleton of joints, the standard method for character animation in games.

Skeletal editing

Skeletal editing is a class of organic chemistry reactions that insert, delete, or swap single atoms within a molecule's carbon framework, important in drug discovery.

Skeletal editing of arenes by nitrene insertion

Skeletal editing of arenes by nitrene insertion is a family of reactions that inserts one nitrogen atom into an aromatic ring, as in arene-to-pyridine conversion.

Skeletal editing via nitrogen deletion

Skeletal editing via nitrogen deletion is a synthetic strategy that removes a nitrogen atom directly from a molecule's ring or chain, converting it into a new skeleton.

Skeletal Ewing sarcoma

Skeletal Ewing sarcoma, also called Ewing sarcoma of bone or pPNET, is an EWSR1-ETS fusion-driven small round cell tumor of bone in the young; distinguished from extraosseous Ewing sarcoma by primary site and somewhat worse prognosis.

Skeletal fluorosis

Skeletal fluorosis (ICD-11 FB80.1) is chronic fluoride toxicity of bone from high water, tea, coal, or occupational exposure, causing osteosclerosis, ligament calcification, pain, deformity, and fracture risk.

Skeletal formula

The skeletal formula, also known as the bond-line formula or line-angle formula, is a two-dimensional shorthand for molecular structures in which carbon atoms and their hydrogens are omitted.

Skeletal muscle

Skeletal muscle: voluntary striated muscle tissue, over 600 muscles of multinucleated fibers; sarcomeres with actin-myosin sliding filaments, type I/II fiber types, myokine endocrine role, sarcopenia and muscular dystrophies.

Skeletal muscle fiber

Skeletal muscle fiber (myofiber, muscle fiber): a large multinucleate muscle cell formed by myoblast fusion, containing myofibrils and sarcolemma. Types I, IIA, IIX (formerly IIB) classified by myosin heavy chain or mATPase; highly plastic, sex- and age-dependent.

Skeletal muscle myoblast

Skeletal muscle myoblast (skeletal myoblast, CL:0000515), a mononucleated progenitor that differentiates and fuses into multinucleate skeletal muscle fibers; derived embryonically from somites and postnatally from satellite cells.

Skeletal muscle satellite cell

The skeletal muscle satellite cell (myosatellite cell) is the resident stem cell of skeletal muscle, discovered in 1961 by Mauro and Katz, lying between basal lamina and sarcolemma, quiescent until activated to supply myoblasts for muscle growth and repair.

Skeletal Muscle Ventricle

Skeletal Muscle Ventricle (SMV), an autologous skeletal-muscle pumping chamber, usually latissimus dorsi, electrically conditioned and connected to assist a failing heart; experimental alternative to mechanical ventricular assist devices.

Skeletal survey

A skeletal survey is a series of about twenty X-ray images of the entire skeleton, used mainly to detect fractures in suspected child abuse and bone disease in multiple myeloma.

Skeletal traction

Skeletal traction is an orthopedic treatment in which a pin or wire inserted directly into bone applies a steady pulling force to align a fracture or immobilize a limb.

Skeletochronology

Skeletochronology estimates the age and growth history of amphibians, reptiles, fish, and other vertebrates by counting annual growth lines in bone cross-sections, formally introduced by Castanet and Smirina in 1990.

Skeletogenic cell

Skeletogenic cell (Cell Ontology CL:0007001): umbrella term for cells forming skeletal tissue, including osteoblasts, chondroblasts, and chondrocytes, arising from skeletal stem and progenitor cells in periosteum and bone marrow.

Skeleton

A skeleton is the system of structures supporting an animal's body, protecting its organs, and enabling movement, taking three forms: hydrostatic skeleton, exoskeleton, and endoskeleton.

Skeleton (sport)

Skeleton: head-first, prone ice-track sliding sport invented at St Moritz in the late 1800s on the Cresta Run; Olympic in 1928, 1948, and permanently since 2002, governed by the IBSF.

Skeleton Coast

Skeleton Coast: northern Atlantic shore of Namibia, about 500 km from the Ugab to the Kunene River, famed for Benguela Current fog, whale bones and shipwrecks such as the Eduard Bohlen and Zeila, largely within Skeleton Coast National Park.

Skeleton key

A skeleton key is a key filed down so its bit can pass the wards of a warded lock, often opening many locks of the same type.

Skeleton Key attack

Skeleton Key is a universal jailbreak technique for large language models, disclosed by Microsoft in 2024, which convinces models to answer any request with a warning instead of refusing.

Skeleton Knight in Another World

Skeleton Knight in Another World (骸骨騎士様、只今異世界へお出掛け中) is a Japanese isekai fantasy by Ennki Hakari about gamer Arc, trapped in his skeleton-knight MMO avatar, with manga, and a 2022/2026 two-season anime.

Skeleton panda sea squirt

Skeleton panda sea squirt (Clavelina ossipandae, gaikotsu-panda-hoya), a colonial ascidian described in 2024 from Kumejima Island, Japan; transparent zooids with rib-like white blood vessels and panda-like black markings; not Clavelina polycitorella.

Skeleton Tree

Skeleton Tree is a 2016 studio album by Nick Cave & The Bad Seeds, written largely before the death of Cave's 15-year-old son Arthur in 2015.

Skeleton-based action recognition

Skeleton-based action recognition classifies human actions from time sequences of body-joint coordinates rather than raw video. It is robust to lighting and background changes, efficient, and privacy-friendly.

Skeleton-of-Thought

Skeleton-of-Thought (SoT) is a decoding method for large language models, introduced in 2023 by Microsoft Research and Tsinghua University, that speeds up generation by expanding outline points in parallel.

Skeletonization

Skeletonization: the evolutionary origin and development of animal skeletons, covering hydrostatic, exoskeleton, and endoskeleton designs, vertebrate endoskeleton versus exoskeleton, Ordovician arandaspids, and biomineralization toolkit origins.
