Accessory organ of the digestive system that is both an endocrine and exocrine gland components of bile - ANSWER minerals, bile pigments, bile acids (salts), phospholipids, cholesterol hepatic sinusoids - ANSWER blood filled channels between the layers of hepatocytes in the liver chymotrypsin and trypsin - ANSWER pancreatic enzymes that digest proteins hepatic lobules - ANSWER microscopic s...

How are the amino acid-based and the steroid hormones different from each other (e.g. chemical properties; transport in the blood; interactions with target cells)? - Amino acid hormones: water soluble, unbound in blood, short duration effect, needs second messenger to send signal to nucleus for transcription Steroid hormones: lipid soluble, bound in blood to protein carriers for transport, prolonged effect I gave one example of a second messenger in the voicethread. Try to find another exam...

CNS - ANSWER consists of the brain and spinal cord; processes information and determines if and how the body should respond by issuing commands to muscle and gland cells PNS - ANSWER a subdivision of the nervous system that is composed of all nerves and ganglia; divided into sensory and motor divisions Sensory (afferent) - ANSWER specialized neurons that detect stimulus (light, heat, pressure, and chemicals) and transmit information about them to the CNS motor (efferent) - ANSWER neuron...

chondrocytes - found in healthy cartilage; make up the matrix; facilitate the exchange of fluids through gelatinous layers; not capable of cell division tension - stretching of the muscle that are resisted by collagen fibers; aka pulling forces compression - pushing the bones toward the middle, resisted by cartilage torsion - twisting stress put on bones; collagen fibers provide resistance to it as a unit diaphysis - middle part or shaft of a bone epiphysis - head or end of a bone epiphys...
