IVY TECH APHY 101 FINAL EXAM

A ball-and-socket joint is also called an ellipsoidal joint. - false A molecule that carries energy in a form the cell can use is - ATP A motor unit is - a motor neuron and all the muscle fibers it innervates A mutation can cause disease if - the DNA sequence changes so that one amino acid is substituted for another in a way that affects the encoded protein's functioning. A person is exposed to a drug that prevents vesicles from forming in neurons. Predict the effect this will have on nerve function. - Neurotransmitters won't be released into the synapse via exocytosis. A pole vaulter keeps track of his position in mid-air through - proprioceptors A protein is formed from a sequence of amino acids. - true A soldier suffers a brain injury, and becomes unable to speak. The damage is likely in - Broca's area A test organism develops a genetic mutation that causes neurons to develop without synaptic knobs. How will this impact neuronal function? - No neurotransmitters will be released into the synapse to signal the postsynaptic neuron, as the synaptic knob is where they are stored. A tooth root attached to a jawbone by a periodontal ligament is a __________ . - gomphosis Action potentials are related to impulses conducted along an axon in that - propagation of a series of action potentials along a nerve fiber constitutes an impulse. Blood with excess oxygen causes cyanosis. - false Bones of a synovial joint are held together by - joint capsule Cartilage tissues are likely to be slow in healing following an injury because - chondrocytes do not have direct blood supplies. Cell membranes are described as a fluid mosaic that maintains stability while still allowing movement. What component maintains most of the flexibility of the membrane? - phospholipid bilayer
