CanColl May12 MCQ AP1 A
| Question | Answer |
|---|---|
| homeostasis | condition in which body's internal environment remains within certain physiological limit i.e. equilibrium |
| stress | any stimulus that creates an imbalance in the internal environment |
| biology | the study of living organisms |
| histology | the study of the structure of cells and tissues |
| immunology | the study of the body's defense mechanisms |
| physiology | the study of the function of body parts |
| anatomy | the study of the structures and relationships between the structures of the body |
| ion | an atom that has gained or lost an electron |
| stem cells | cells that have the ability to maintain a constant population of newly differentiating cells |
| pinocytosis | cell drinking |
| phagosytosis | cell eating |
| codon | in the mRNA molecules, each set of three consecutive nucleotide bases |
| anti-codon | one end of the tRNA carries a specific amino acid and the other has three nucleotides |
| diffusion | spreading - natural tendency of small particles to spread out evenly within any space |
| osmosis | net diffusion of water thru a selectively permeable membrane |
| unipolar neuron | only one process from the cell body |
| bipolar neuron | one dendrite and one axon |
| multipolar neuron | multiple dendrites - and one axon |
| exocytosis | secretory vesicles form inside the cell, which fuse with the cell wall and release their contents (waste substances) into the ECF |
| white matter | aggregation of myelin |
| grey matter | neuron cell bodies, dendrites and axon terminals that are unmyelinated |
| absolute refractory period | period during which a second action potential cannot be initiated |
| relative refractory period | period during which a second action potential can be initiated by only with a supra-threshold stimulus |
| direction of a nerve impulse | dendrite to axon |
| Nerve fibers "A" | large diameter, myelinated - energy efficient |
| Nerve Fibers "B" | medium diameter, myelinated |
| Nerve Fibers "C" | small diameter, unmyelinated - slowest |
| types of forces | shear, compression and tensile |
| 3 types of muscle | skeletal (striated/vol) cardiac (striated/nonvol) smooth (non-striated/nonvol) |
| what is threshold for AP | critical level (about -55 mV) for an action potential to arise in the trigger zone aka axon hillock |
| Tendon connects | muscle to bone |
| ligament connects | bone to bone |
| what is a motor unit | a motor neuron and the skeletal mm fibres that it stimulates |
| whagt is the direction of signal in a motor unit | CNS - to- PNS |
| node of ranvier | nodes between myeline sheaths on axons |
| what is the purpose of an action potential | it carries commands or sensory info to and from the brain. |
| where is calcium stored in the resting muscle | sarcoplasmic reticulum |
| what neurotransmitter is released at the neuromuscular junction NMJ | acetycholine ACh |
| what is the epithelial tissue layer of the epidermis made up of | keratinized, stratified, squamous epthielium |
| what are melanocytes | cells in the epidermis that produce melanin - produces colour in the skin |
| what are the two regions of the dermis | superior layer is the papillary region and the deeper layer is called the reticular region |
| what makes up the lymphatic system | lymph vessels, lymph nodes, thymus, and spleen |
| What is the function of the thymus | located between the lungs - as part of the lymphatic system - it's primary purpose is to make T cells. |
| how many lymph nodes are in the body | approx 600 |
| what is the function of the lymph nodes | filters lymph - and creates B cells |
| what is the function of the spleen | located on the left side of the upper abdomen, the spleen produces T & B cells aka lymphocytes, macrophages and plasma cells |
| what is the purpose of the lymphatic system | carries out immune responses, transports dietary lipids, drains excess interstitial fluid. |
