BIO exam 2
| Question | Answer |
|---|---|
| Blood | connective tissue consisting of plasma |
| Dense Irregular | thicker fibers and forms protective capsules and organs |
| Loose Connective | supports epithelial and organs and surrounds blood vessels, and nerves |
| Adipose | tissue that stores fat |
| nerve tissue | neurons and junk |
| organ | consists of two or more tissues arranged in a way that allows the organ to carry off specific tasks |
| Tissue | a group of cells that perform a certain task |
| Simple squamous epithelium | lines blood vessels, the heart, air sacs in the lungs |
| Skeletal Muscle | striated, voluntary movement |
| Simple cuboidal epithelium | lines the kidneys, ducts of reproductive tract, and functions in absorption/secretion, movement of a material |
| Simple columnar epithelium | lines some airways, parts of the gut. Functions in absorption, secretion, and protection |
| Cardiac Muscle | heart, composed of short striated fibers, functions in units |
| Smooth Muscle | not striated, lines the gut, blood vessels, and glands |
| Ganglion | cluster of nerve cell bodies |
| Endocrine gland | secretes hormones |
| Exocrine gland | secretes milk, sweat, spit |
| Dense regular tissue | fibers are parallel and are arranged as muscle to bone (WAVY) |
| Myelin sheath | insulates axons and speeds connections of action potentials |
| synapse | link between neurons |
| neuron muscular junction | something about electricity |
| Neurotransmitter | chemical signals released by axon potentials |
| dendrite | receives chemical signals sent by other neurons |
| axon | transmits electric signals along the length of its body |
| example of animals with a hydrostatic skeleton | earthworms and any type of cnidarian |
| Cerebellum | controls rapid movement, posture and balance |
| hypothalamus | "survivor" behavior, like thirst, sweat, hunger, and sleep |
| Broca's Area | speech production, left hemisphere, language |
| Medulla Oblongata | controls breathing, heart rate, digestion |
| Pons | controls rate and depth of respiration |
| thalamus | relays sensory signals to and from the cerebral cortex. |
| Membrane potential | voltage diff. across a neuron membrane. |
| Action potential | abrupt reversal of change difference across a resting membrane |
| Threshold Potential | gated sodium channels open causing action potentials |
| Resting potential | neuron is at rest |
| cartilage | dense array of fibers in a jello substance |
| Central nervous system | brain and spinal cord |
| cephalization | neurons that detect information which gets concentrated in the head of humans |
| bone | store minerals, salts, produces blood cells, provides spaces for its own living osteocytes |
| amino acid-derived hormone | amine, peptide, protein that functions as a hormone |
| animal hormone | intercellular signaling molecule that is secreted by an endocrine gland or a cell that travels in blood |
| Steroid hormone | lip-soluble hormone derived from cholesterol |
| releasing hormone | encourages secretion of another hormone by its target cell |
| inhibiting hormone | discourages secretions of another hormone by its target cell |
