Neurons, Synapses, Signaling
(NSS 1)
(NSS 1)
These branched extensions of a neuron receive incoming signals from other neurons.
What are dendrites?
This division of the nervous system includes the brain and spinal cord.
What is the central nervous system (CNS)?
These receptors detect physical deformation such as touch and vibration.
What are mechanoreceptors?
These thin filaments in muscle fibers are primarily made of this protein.
What is actin?
This animal has a 90% success rate while hunting.
What is a dragonfly?
This structure is the cone-shaped base of the axon where action potentials are typically generated.
What is the axon hillock?
These cells support, nourish, and regulate neurons.
What are glial cells (glia)?
This term describes the conversion of stimulus energy into a change in membrane potential.
What is sensory transduction?
This model describes how thick and thin filaments slide past each other during contraction.
What is the sliding-filament model?
Who is Brandon?
These proteins span the membrane and allow specific ions to pass, contributing to the resting potential.
What are ion channels?
This evolutionary trend involves the concentration of sensory and neural structures at the anterior end.
What is cephalization?
This structure in the inner ear contains hair cells that detect sound waves.
What is the organ of Corti?
This ion binds to troponin, causing tropomyosin to shift and expose binding sites.
What is calcium (Ca²⁺)?
This newly researched barrel-shaped cellular structure can hold and preserve mNRA for 7 days without degradation.
What is a vault or a vault ribonucleoprotein particle?
This type of postsynaptic potential moves the membrane potential closer to threshold.
What is an excitatory postsynaptic potential (EPSP)?
This brain region acts as the pacemaker for circadian rhythms.
What is the suprachiasmatic nucleus (SCN)?
This part of the retina is responsible for high-acuity vision and contains many cones but no rods.
What is the fovea?
This structure is the functional unit of a muscle fiber, made of repeating segments.
What is a sarcomere?
Scientist have recently published a paper giving this animal cocaine and benzoylecgonine
What is a salmon?
This process combines multiple postsynaptic potentials to determine whether an action potential will occur.
What is summation?
This structure connects the two hemispheres of the brain and allows communication between them.
What is the corpus callosum?
This term describes the brain’s interpretation or construction of sensory input.
What is perception?
This process increases muscle force by activating more motor neurons.
What is recruitment?
The TA who can sing the alphabet backwards.
Who is Emi
