Unit 1 (Intro)
The 3 types of cell junctions
What are anchoring, gap, and tight junctions?
approx. -90 mV
What is the equilibrium potential for K+ in a typical neuron at rest?
The regulatory proteins that F-actin associates with
What is Troponin and Tropomyosin
Minimum volume in ventricle at the end of ventricular contraction
What is End Systolic Volume (ESV)?
These two hormones regulate the changes in calcium that influences cardiac muscle contractions
What are epinephrine and norepinephrine?
Intercalated discs are unique to this type of tissue (be specific)
What is cardiac muscle?
The potential that decreases the chance of exciting the axon to “fire” or depolarize.
What is Inhibitory Post Synaptic Potential (IPSP)?
Pi is released, myosin rotates on hinge, swings back, pulling actin along with it towards the m line in this action
What is a power stroke?
When using a sphygmomanometer, the turbulent flow results in these sounds
What are Korotkoff sounds?
The three domains of a membrane-spanning receptor
What are the extracellular, transmembrane, and intracellular domains?
A response that sends a signal which reinforces the stimulus
What is positive feedback?
Epithelial cells that produce cerebral spinal fluid (CSF)
What are Ependymal cells?
A muscle contraction that usually occurs when the load is greater than the force that can be applied
The inflammation of the touch membranous sac surrounding the heart
What is pericarditis?
Cytokines released by one WBC (leukocytes) to act on another WBC
What are interleukins?
Nucleotides that act as neurotransmitters.
What are purines?
Muscular Dystrophy is characterized by a lack of this protein
What is dystrophin?
What are cytokines?
Name of equation to calculate electrical potential of the cell needed to generate an equilibrium state
What is the Nernst Equation?
Histamine is an example of this type of signaling molecule
What is paracrine?
4 amino acids that function as neurotransmitters in the CNS.
What is glutamate, aspartate, glycine and gamma-aminobutyric acid (GABA)?
The two factors that vary the contraction of the muscle
What are the type of motor units activated and the number of motor units that are active?
What is Frank-Starling Law?
State that occurs when there is a defect in Na+ channel where the channel stops functioning during excitation and the muscle stays depolarized
What is hyperkalemia?
