Conn syndrome: Overproduction of the hormone aldosterone by a tumor in the outer portion (cortex) of the adrenal gland. The excessive aldosterone results in low potassium levels (hypokalemia), underacidity of the body (alkalosis), muscle weakness, excessive thirst, excessive urination, and high blood pressure. Also known as aldosteronism and hyperaldosteronism.
Connectionism: A theory of information processing that is based on the neurophysiology of the brain. The basic tenets of connectionism are that signals are processed by elementary units (in this case, neurons), processing units are connected in parallel to other processing units, and connections between processing units are weighted. The weights may be hard-wired, learned, […]
- Connective tissue
Connective tissue: A material made up of fibers forming a framework and support structure for body tissues and organs. Connective tissue surrounds many organs. Cartilage and bone are specialized forms of connective tissue. All connective tissue is derived from mesoderm, the middle germ cell layer in the embryo.
- Connective tissue disease
A disease (autoimmune or otherwise) that attacks the collagen or other core components of connective tissue. Lupus is a connective tissue disease.
- Connective tissue disease, heritable
Connective tissue disease, heritable: See: Heritable connective tissue disease.
Connexin: A subunit of connexon, a protein that forms a gap junction, a channel that permits ions and small molecules to move between adjacent cells. The connexins are important to intercellular communication. Historically, gap junctions were first characterized by EM (electron microscopy). They appeared to be specialized structures in the plasma membranes of cells in […]
