What separates the pleural membranes?
The intrapleural space filled with intrapleural fluid
What is the function of intrapleural fluid?
Prevents the two membranes from rubbing against one another
What illness can cause inflammation of the pleurae?
Pneumonia
What is the condition called when the pleurae become inflamed?
Pleurisy
What symptom can result from pleurisy?
Chafing and painful ventilation
Sattler’s veil
- colored fringes seen around bright lights due to corneal edema
(Visual phenomenon that occurs as a result of central corneal epithelial edema)
What are facultative anaerobes?
Bacteria capable of using oxygen but can also thrive using anaerobic respiration
They are dispersed throughout a culture tube with the greatest concentration at the top.
Where would you find the greatest concentration of facultative anaerobes in a test tube?
At the top of the tube
This is due to aerobic respiration yielding a more favorable energy result.
What are obligate aerobes?
Bacteria that require oxygen to survive
They gather at the top of the culture tube where oxygen levels are highest.
Describe the distribution of obligate aerobes in a test tube culture.
Bacteria gather at the top
This is where the oxygen levels are greatest.
What are microaerophiles?
Bacteria that utilize oxygen only at lower concentrations
They show the greatest concentration towards the upper portion of the test tube, but not at the very top.
Where would you find the greatest concentration of microaerophiles in a test tube?
Towards the upper portion, but not at the very top
This reflects their need for lower oxygen concentrations.
What are strict anaerobes?
Bacteria that cannot tolerate oxygen and rely on anaerobic respiration
They display the greatest concentration towards the bottom of the culture tube.
Where would you find the greatest concentration of strict anaerobes in a test tube?
Towards the bottom of the tube
This is where the least amount of oxygen is present.
What are aerotolerant organisms?
Bacteria that can grow in the presence of oxygen but do not utilize it for respiration
They are evenly distributed throughout a test tube liquid culture.
How are aerotolerant organisms distributed in a test tube culture?
Evenly distributed throughout the culture
They do not utilize oxygen despite being able to grow in its presence.
What is the simplest form of a reflex arc?
Monosynaptic
How many synapses are involved in a monosynaptic reflex arc?
One
What type of neuron synapses directly onto a motor neuron in a monosynaptic reflex?
Sensory neuron
What allows for an almost instant reaction to sensory input in a monosynaptic reflex?
Direct synapse between sensory and motor neurons
Can monosynaptic reflexes be inhibited?
Yes
What is an example of cognitive override in a reflex action?
Deciding not to drop a hot plate
What do reverberating circuits create?
A synapse loop
What is an example of neuronal activity involving reverberating circuits?
Eye muscle twitching while asleep
