Nervous System
The structural Classification of the nervous system includes these two sections
What is CNS and PNS?
The anterior pituitary produces __(#)____ hormones.
What is 6?
The gland that produces tears in the eye.
What is the lacrimal gland?
Resting membrane potential
What is -70mV?
What is the optic nerve?
The term central nervous system refers to these two organs
What is brain and spinal cord?
Prolactin is secreted from this gland.
What is the anterior pituitary gland?
The outermost tunic seen anteriorly as the "white of the eye".
What is sclera?
Threshold potential
What is -55mV?
The brain and spinal cord are protected by three connective tissue membranes that are called...
What are meninges?
The neuron processes that normally receive incoming stimuli.
What are dendrites?
This controls the pituitary gland.
What is the hypothalamus?
A cold can cause an ear infection when it passes through the auditory tube in what part of the ear?
Na+ gates rapidly open, flooding the cell with that ion. Membrane potential rapidly rises to +30mV.
What is depolarization?
This helps us to detect changes in our balance and body orientation
What is the semicircular canals?
Cells in the PNS are myelinated by these specialty cells that increase the rate at which action potentials propagate
What are schwann cells?
Alcohol inhibits the secretion of this hormone.
What is Antidiuretic hormone?
What is the retina?
K+ gates slowly close; the membrane potential dips to around -90mV.
What is hyperpolarization?
Auditory nerve messages are interpreted in this part of the brain
What is the temporal lobe?
2 FUNCTIONAL classifications of motor division of the peripheral nervous system
What is Autonomic and Somatic?
Gonadotropic hormones are released by this gland
What is anterior pituitary gland?
Tympanic Membrane & Ossicles are located here.
What is the middle ear?
Na+ gates close and K+ gates open, the charge of the membrane begins to reverse, becoming more negative.
What is repolarization?
These 2 hormones are released by the thyroid gland.
What is Calcitonin and Thyroid hormone?
My arm pulls away from a heat source - the muscle is stimulated by these nerves.
What are motor (efferent) neurons?
This stimuli refers to the release of hormones in response to other hormones being released.
What is Hormonal stimuli?
Vibrations from the tympanic membrane are transferred to the inner ear in this order.
What is hammer, anvil, stirrup, oval window?
What is the Na+/K+ pump?
The pancreas produces this when there is not enough glucose in the blood
What is glucagon?
Correct sequence of stimulus transfer in a typical reflex arc.
receptor, sensory neuron, interneuron, motor neuron, effector
The hormone that triggers ovulation in the female.
What is the LH hormone?
Transparent anterior portion of the sclera.
What is cornea?
Action potentials will propagate in this way? Harry Styles knows...do you?
What is one direction?
Goiters are primarily the cause of this deficiency; thyroxine is not ale to be produced without it!
What is iodine?
What are neurons and neuroglia?
Calcitonin is secreted by this gland.
What is thyroid gland?
The structure that regulates the amount of light that enters the eye.
What is iris?
This helps to speed up action potentials.
What is myelination or Schwann Cells?
This one is a tough one to SWALLOW.
What is the hypoglossal nerve?
