Depolarization of the Axon shifts the membrane potential towards …. -90mV -85mV -70mV 0 mV
The brachial plexus serves the following areas: Neck & Shoulder Girdle Shoulder Girdle & Arm Neck & Arm Thorax & Arm
The Synaptic vesicles attach to the pre-synaptic membrane after: Calcium ions leave the cytoplasm Calcium entering the synaptic terminal Reabsorption of calcium in the endoplasmic reticulum Active transport of calcium into the synaptic vesicles
Spinal nerves are mixed nerves when they contain: White matter and gray matter Both dorsal and ventral roots Both sensory and motor fibers Ascending and descending pathways
Spinal nerves from the sacral region of the cord communicate with the ________ muscles. Shoulder Intercostal Abdominal Leg
Damage to the ventral root of a spinal nerve: Blocks the output of the skeletal muscle Disables the spinal cord to process information Blocks the sensory input Disables the brain to communicate with the spinal cord
Autonomic center that controls blood pressure, heart rate and digestion: Medulla Oblongata Pons Mesencephalon Cerebellum
Sensory information is processed and relayed to the cerebrum by the: Midbrain Thalamus Pons Cerebellum
What connects the third & Fourth Ventricle? Central Canal Interventricle foramina Cerebral aquaduct Tentorium cerebelli
Which of the following 2nd Ventricles will form the Medulla Oblongata? Diencephalon Mesencephalon Myelencephalon Telencephalon
CSF …. Is secreted by the choroid plexus Is formed by a passive process Contains blood cells and blood plasma Is normally produced twice as fast as it is removed
The auditory cortex is in the … Frontal Lobe Temporal Lobe Parietal Lobe Occipital Lobe
Which system of the brain deals with memory and emotions? The Prefrontal lobe The Limbic system The Thalamus The Temporal Lobe
How many pairs of spinal nerves do we have? 31 6 12 22
Vision problems occur if the _______ nerve is damaged. Optic Oculomotor Trochlear Abducens
