31, 12
Axons contain
Presynaptic Terminals that contain neurotransmitters. They are wrapped in myelin.
Most of nerve cells within CNS and afferent neurons are mostly
Afferent and Multipolar Neurons
Which of the reflexes is the basis for several tests used in neurological examination
The Stretch Reflex
The transparent anterior portion of the fibrous tunic with more proteoglycans is the
Cornea
The outermost tunic of the eyeball is the
the fibrous tunic
The outermost tunic of the eyeball that helps maintain the shape of the eye
Sclera (Fibrous Tunic)
A neuron that carries action potentials from one neuron to another is called a _
sensory neurons
Epinephrine and dopamine are types of neurotransmitter known as
Monoamines or Biogenic amines
Is the retention of motor skills such as how you type on a keyboard and tie your shoes
Procedural Memory
The cranial nerves which regulate eyeball movement
The Abducens (VI) nerves
Synaptic vesicles contain neurotransmitter are present in the
Axon terminal/presynaptic vesicles in the axon of the neuron
Which neuroglial wraps myelin sheath around an axon?
Oligodendrocytes
Which of the following is (are) associated with retina?
- inner nervous tissue: Sensory Retina (contains The Photoreceptor Neurons, The Bipolar Neurons and The Ganglion Neurons.)
- outer, pigmented layer: Pigmented Retina.
- The Dendrites of the photoreceptor neurons are called Rods and Cons
The cranial nerves that relay nerve impulses to thoracic and abdominal viscera
The Vagus (X) nerves
Which is not a neuroglial cell of the CNS?
Anything other than astrocyte, ependymal cell, microglia oligodendrocyte
The part of the ear that collects sound waves and directs them to the meatus is called
The external ear collects sound waves and direct them inward. It consists of the Auricle or Pina, the external Auditory canal (External Acoustic Meatus), and the Tympanic membrane.
What is ganglia made of?
Collection of cell bodies in PNS surrounded by Neuroglia
Neurons located in the retina of eye and the nasal cavity are
Bipolar Neurons
The patellar or the stretch reflex is a classic example of
Knee jerk reflex? The simplest reflex? Monosynaptic reflex arcs?
Which of the reflexes is the basis for several tests used in neurological examination
The Stretch Reflex
The lacrimal glands….
The gland produces tears, at a rate of 1 ml/day, which are used to wash away foreign objects, to moisten the surface of the eye and lubricate the eyelids.
Contains salt, some other stuff and Lysozyme
The most superficial meningeal layer is the
Dura matter
What is the dura mater?
The outermost cranial meninges. Fibrous and tough.
The raised ridges on the cerebral hemispheres called gyri are located in what part of the brain
Cerebrum
The cranial nerves responsible for changes in pupil size and shape of lens
The Oculomotor (III) nerves
The nervous system
It is a major regulatory system that detects sensation and controls movements, physiologic processes, and intellectual functions.
It consists of the brain, spinal cord, nerves and sensory receptors
The type of circuit, in which input from many different neurons is funneled into one or single postsynaptic neuron.
Converging Circuit
Which of the following cranial nerves innervates an eye muscle
the abducens, the trochlear, and the oculomotor
There are _______ pairs spinal nerves and _______ pairs of cranial nerves
31, 12
The vascular tunic with large amount of pigment and numerous blood vessels is the
the Uvea (The Choroid, The Cillary Body and The Iris)
The cranial nerves which convey nerve impulses related to head and shoulder movements
The Accessory (XI) nerves
Which of the following special senses is relayed directly to the cerebral cortex without going to the thalamus?
Olfaction
Which of the following is not a part of external ear?
Anything other than: The Auricle or Pina, the external Auditory canal (External Acoustic Meatus), and the Tympanic membrane, also called Eardrum.
Neurons that have a single axon and a single dendrite are
Bipolar neurons
Which is the main function of the limbic system
basic survival functions such as Reproduction, Nutrition and Memory. It is also involved in Emotions.
The part of the brain that connects the medulla to the midbrain is the
the brainstem or cerebral peduncle
The sensory (afferent) division of PNS
division transmits electrical signals known as Action Potentials from sensory receptors to the CNS.
The second largest part of the brain and called little brain is
cerebellum
