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

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
Cranial Nerve X controls the Heart, Lungs, Liver, Stomach and intestines. • Facial • Trigeminal • Vagus • Olfactory
The surface of the post-central gyrus (Humunculus) contains the …… • Primary motor cortex • Visual cortex • Olfactory cortex • Primary sensory cortex
The Third Ventricle is located… • Within the hemispheres of the cerebrum • Between cerebellum and pons • In the Diencephalon
Neuroglia … • Conduct impulses • Are helper cells • Send messages • Break down neurotransmitters
The transmembrane potential within the Axolemma in a resting neuron is • Positive • Negative • Zero
The Axon is connected to the Soma at the • Dendrites • Axon hillock • Synaptic terminal • Synaptic vesicle
Neurotransmitter are stored within… • The axon • The Axon terminal • The vesicles • Within the Synaptic cleft
