three types of muscle - skeletal cardiac smooth basic function of muscle - generate tension functions of skeletal muscle - locomotion facial expression posture and body position regulation of body temperature voluntary contraction - requires nervous system input some skeletal muscles are automatic, but we have the ability to change their activity (ex: diaphragm) muscles pull or push? how do you predict the action of a muscle? - pull predict the action of a muscle based on location or...

What are the two main cell types in the nervous system? - ANSWER -Neurons -Neuroglia What are the parts of the neuron? - ANSWER -Cell body: processes information -Dendrites: collects information -Axon: propagates information -Synapses: transmits information

Two main cell types - ANSWER neurons and neuroglia the axon - ANSWER dendrites are these branch-like regions if the cell which collect info from other neurons. that info is sent to the cell body where it is processed. the axon is an extension of the cell which propagates the info down toward the axon terminal. the axon terminals form synapses with other dendrites to transmit the info Bioelectricity - ANSWER the basis of which are the charged ions inside and outside the cell. membrane poten...
