What is dura mater, arachnoid mater, and pia mater
100
nerve grouping that innervates the lower extremities
What is lumbar plexus
100
these receptors detect light
What are photoreceptors
100
Ability to detect motion like acceleration, turning, and spinning
What is dynamic equilibrium
200
triangular region where axon attaches to cell body and exits the cell body. Has no Nissl Bodies.
What is an axon hillock
200
these two convolutions of the brain increase the surface area
What is gyri and sulci
200
posterior and anterior ramus combine to form this structure
What is a spinal nerve
200
contains many blood vessels, can give the eye a “bloodshot” look
What is conjunctiva
200
specific region that transfers sound signals to temporal lobe to interpret
What is basilar membrane of the spiral organ
300
between sensory and motor neurons, help transmit information to the brain for further processing
What are interneurons
300
Primary visual area of brain
What is occipital lobe
300
sheath around single nerve fiber and their myelin sheaths
What is the endoneurium
300
cause of color the vision "blind spot"
What is optic disk, region where the optic nerve takes information from the eye to the brain. Has no photoreceptors
300
Determines acceleration in different directions (spinning, flipping, or cartwheels)
What are the semicircular ducts
400
This type of neuron is found in the nose (sense of smell) and eye (vision)
What is bipolar neuron
400
center for controlling respiratory rate, blood pressure and other vital centers. It is also a location where information travels from one side of the brain to the other.
What is the medulla oblongata
400
A cycle that is involuntary and represented by these phases: Receptor, Sensory neuron, Integrating center, Motor neuron, Effector
What is Reflex Arcs
400
These two structures help maintain the exterior eye
What is lacrimal apparatus (Nasolacrimal Duct, Lacrimal gland)
400
Senses change in head position. If the visual cues and are not synchronized to it then a sense of imbalance results (nausea)
What is the vestibule
500
these cells allow the transmissions to jump from node to node and increases the speed of the neuron in the PNS
What are Schwann cells
500
Controls the muscles involved in speech. Located on the left lobe. Contains the motor homunculus
What is the Broca Area
500
Region of spinal cord that is a continuation of L1-S5
What is cauda equina
500
determine motion and shape of objects, sight in dim light
