Neurophysiology Study Guide 1. Define "equilibrium potential". Why is the resting potential closer to the potassium equilibrium potential (EK+) than the sodium potential (ENa+)? The equilibrium potential is the point at which the force exerted on an ion by electrostatic and concentration gradient forces are balanced‚ and there is no net movement of that ion. The resting potential is closer to EK+ than ENa+ because the cell membrane is more permeable to

Osmosis & Diffusion Review Sheet Name: Fill in the Blank away low high hypertonic hypotonic diffusion molecules osmosis vacuole water solute permeable towards semi-permeable concentration gradient 1. The cell membrane regulates and controls what kind of molecules ______ move in & out of the cell. 2. When molecules spread from an area of high to low concentration‚ it is called _Diffusion_____. 3. As molecules diffuse‚ they create a _concentration gradient_____

Cranial Nerves The brain and spinal cord (CNS) are connected to parts of the body by nerves and cell bodies called the peripheral nervous system. The PNS contains all of the nervous tissue outside the brain and spinal cord. Afferent (sensory) nerve fibers-conduct nerve impulses toward the CNS Efferent (motor) nerve fibers-conduct nerve pulses away Sensory Somatic System – Carries nerve impulses from the senses to the CNS and also carries the impulses to the skeletal muscles and glands

voltage at which you first saw an action potential? 3.0 V 3. How does this tracing compare to the one that was generated at the threshold voltage? The tracing travel in the same fashion but the tracing were different with an increase threshold voltage 4. What reason can you give for the change? Increase voltage 5. Record this maximal voltage here: 6.0 V Activity 2: Mechanical Stimulation 1. When the glass rod is touching the nerve‚ what do you see on the oscilloscope screen? The nerve’s action

Review Sheet for Wuthering Heights 1. What techniques are used in the characterization of Heathcliff? Effects? Heathcliff is associated with evil and darkness from the beginning of the novel. "I felt his black eyes withdraw so suspiciously under their brows." (1) When Lockwood sees Heathcliff’s garden (perhaps a symbol for Heathcliff) "the earth was hard with a black frost the air made me shiver through every limb." (6) When we see Heathcliff when he is first brought into the Earnshaw household

Within the body‚ there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured
