Clusters of a ganglionic sympathetic neurons lying along either side of the spinal cord are called sympathetic blink ganglia

Chain

The blank division of the autonomic nervous system is said to function during rest and Digest

Parasympathetic

Drugs known as a beta blockers may be useful for treating

excessive heart rate

Disorders involving the vagus nerve might cause

food to remain in your stomach longer.

Reflexes that activate muscles on the same side of the body as a stimulus are called

ipsilateral

Which ascending tract carries the sensation for fine touch and vibration

posterior (dorsal) column

Place in correct order of reflex arc 1 motor neuron activation, 2 sensory neuron activation, 3 sensory receptor activation, 4 information processing, 5 effective response

3, 2, 4, 1, 5

Mary is in an automobile accident and suffers a spinal cord injury. She lost feeling in her lower body. Her doctor tells her that the swelling is compressing a portion of her spinal cord. Which part of the spinal cord is likely to be compressed

Ascending tracts

Based on the motor homunculus, which of the following body regions has the fewest number of motor units involved

Back trunk

Blink are receptors in the aorta that monitor blood pressure

Baroreceptors

Following a head injury, Kevin can think of the word he wants to say but cannot make his mouth form the correct sounds to produce the word. He is mostly suffering from damage to

Borcas area

The adrenal medullae secrete

Both epinephrine and norepinephrine

Pre-ganglionic neurons of the autonomic nervous system are located in

Both the brainstem and lateral grey horns of the spinal cord

The blank reflex complements the flexor reflex by activating contralateral muscles

Crossed extensor

Sensory information from all parts of the body is routed to

The somatosensory cortex

Ganglionic neurons innervate

Glands, smooth muscle, cardiac muscle, adipose tissue

splanchic nerves

Innervate the viscera or internal organs

In order to take notes the primary motor cortex must receive input from the blank first

Premotor cortex

Action potential's from receptors involved in general sensations are interpreted in the

Primary sensory cortex

A person touches you slightly with a feather. What two areas of the brain allow you to feel and interpret this touch

Primary sensory cortex and the somatic sensory association area

You cannot tell when your small intestines shift position as food enters because you do not have any blank there

Proprioceptor's

Secondary neurons synapse in the CNS with an inter-neuron known as

Second order neuron

Sympathetic preganglionic fibers are blank and have a blank axons

Short: myelinated

Most sympathetic affect or junctions release norepinephrine but a significant number release acetylcholine instead. Which of these is an example an organ of the cholinergic type

Sweat gland

The blank nervous system stimulates the arrector Pillai muscles and give you goosebumps

Sympathetic

A pedestrian narrowly avoided being hit by an oncoming car, he noticed that it takes a little while for his heart rate and respiratory rate to return to normal, this is likely because

Sympathetic activation of adrenal medulla has released epinephrine and norepinephrine into the bloodstream

The olfactory cortex is located in the

Temporel lobe

adrenergic
