Skeletal in Biological Definition

Biomechanics

... There are three main types of muscles: skeletal Muscle (striated) Unlike cardiac muscle, skeletal muscle can develop a sustained condition known as ... force appears constant through time. This allows skeletal muscle to develop a wide variety of forces. This ...

Muscle

... cardiac muscle : found within the heart skeletal muscle (or "voluntary"): attached to the ... for short, burst activities. Muscles within the skeletal muscle are also divided into two subtypes: ... information to the central nervous system . skeletal muscle is arranged in discrete groups, examples ...

Skeleton

... In biology , the skeleton or skeletal system is the biological system providing ... or buildings may also acquire skeletons.) skeletal systems are commonly divided into three types - ... (a hydrostatic skeleton ), though hydrostatic skeletal systems may be classified separately from the ...

Marfan syndrome

... affecting height and limb proportions, Marfan syndrome may produce other skeletal symptoms. Curvature of the spine ( scoliosis ) is a common problem, as is ... most common cause of sudden death among Marfan syndrome sufferers. The skeletal and ocular manifestations of Marfan syndrome can also be serious, although ...

Anatomy

... system Nervous system Reproductive system Respiratory system Excretory system Circulatory system Lymphatic system skeletal system ( Human skeleton ) Endocrine system Digestive system Immune system Organs : Anus Appendix Brain Breast ...

Bone

... cancellous (spongy). Cortical (outer layer) bone is compact; the two terms are often used interchangeably. Cortical bone makes up a large portion of skeletal mass; but, because of its density, it has a low surface area. Cancellous bone is trabecular (honeycomb structure), it has a relatively high surface ...

Cartilage

... If cartilage is transformed to bone, the perichondrium becomes the periosteum. Growth / Development Chondrification Most of the skeletal system is derived from mesoderm tissue. Chondrification is the process in which cartilage is formed from condensed mesenchyme tissue, which ...

Cell growth

... of cell size regulation One common means to produce very large cells is by cell fusion to form syncytia . For example, very long (several inches) skeletal muscle cells are formed by fusion of thousands of myocytes . Genetic studies of the fruit fly Drosophila have revealed several genes that are ...

Glucose

... carbon as D -glyceraldehyde. Synthesis The product of photosynthesis in plants and some prokaryotes . Formed in the liver and skeletal muscle by the breakdown of glycogen stores (glucose polymers ). Synthesized in liver and kidneys from intermediates by a process known as ...

Glycolysis

... , where reactions more closely connected to aerobic metabolism occur). Glucose gets into the cell through facilitated diffusion . In some tissues, skeletal muscle for instance, insulin stimulates this process. Follow up The ultimate fate of the pyruvate and NADH produced in glycolysis depends ...

Homeostasis

... level of stress, often generating artificial stresses if the "natural" level of stress is not enough. Examples Thermal regulation : The skeletal muscles can shiver to produce heat if the body temperature is too low. Non-shivering thermogenesis involves the decomposition of fat to ...

Patau syndrome

... may exhibit a split in the iris ( coloboma ), a cleft lip and/or palate , weak muscle tone (hypotonia), an increased risk of heart defects, skeletal abnormalities, and other medical problems. Affected individuals rarely live past infancy because of the life threatening medical problems associated ...

Species

... the same genera varied from each other by just 2.2 percent. Translation of the percentage into an actual number results in an average of just three skeletal differences out of the total 338 bones in the body. Amazingly, 58 percent of these differences occurred in the skull alone. "This is a lot less ...

Y chromosome

... Rarely, males may have more than one extra copy of the Y chromosome in every cell (polysomy Y). The extra genetic material in these cases can lead to skeletal abnormalities, decreased IQ, and delayed development, but the features of these conditions are variable. Repair of the Y chromosome ...
