| Question | Answer |
|---|---|
| Formed by the union of a cranial and spinal root | Accessory |
| Receptors located in epithelium of the nasal cavity | Olfactory |
| Serves the senses of hearing and equilibrium | Vestibulocochlear |
| Helps to refulate blood pressure and digestion | Vagus |
| Turns the eyeball laterally | abducens |
| The obturator and femoral nerves branch frome this plexus | sacral plexus |
| Striking the funny bone mayh cause injury to a nerve of theis plexus | Brachial plexus |
| Trauma to a nerve of this plexus may cause wrist drop | brachial plexus |
| Improper administration of an ingection to the buttocks may injure a nerve of this plexus | sacral plexus |
| The phrenic nerve branches from this plexus | Cervical plexus |
| The three primary levels of neural integration in a sensory system include all of the following | receptor level, circuit level, perceptual level |
| A reflex that causes muscle relaxation and lengthening in response to muscle contraction is called a | Golgi tendon reflex |
| Potentially damaging stimuli that result in pain are selectively detected by | nociceptors |
| Nerves that carry impulses towrd the CNS only are | afferent nerves |
| In a crossed extensor reflex, if the right arm were grabbed it would fles and the left arm would | extend |
| a simple spinal reflex goes along which of the following reflex arcs | receptor, afferent neuron, integration center, efferent neuron, effector |
| A fracture of the ethmoid bone would result in damage to which cranial nerve | olfactory |
| Short preganglionic, long postganglionic fibers | sympathetic |
| collateral ganglia | sympathetic |
| increases blood pressure | sympathetic |
| Decreases heart rate | parasympathetic |
| Causes erection of the penis | parasympathetic |
| preganglionic sympathetic | acetylcholine |
| preganlionic parasympathetic | acetylcholine |
| postganglionic sympathetic to sweat glands | acetylcholine |
| most postganglionic sympathetic | norepinephrine |
| The parasympathetic nervous system is characterized by peripheral ganglia near the | organs and by short postganglionic fibers |
| The parasympathetic ganglionic that serves the eye is the | ciliary ganglion |
| Cardiovascular effects of the sympathetic division include | constriction of most blood vessels, dilation of the vessels seving the skeletal muscles, increase of heart rate and force |
| Contol temperature, endocrine activity, and thirst are functions associated with the | hypothalamus |
| Sympathetic fibers leave the spinal cord in the | thoracolumbar region and the postganglionic fibers secrete norepinephrine |
| Two major classes of adrenergic receptors found in the ANS are | Alpha and Beta |
| The two cholinergic receptor types are | nicotinic and musarinic |
| The white outer tough connective tissue covering of the eyeball | sclera |
| The muscle responsible for altering the shape of the lins | ciliary muscle |
| The vascular coat of the eyeball; deeply pigmented | choroid |
| A muscle that moves the eye ball | rectus muscle |
| The semsory layer of the eye | retina |
| the structure most responsible for focusing light rays that enter the eye | lens |
| Help maintain the intraocular pressure; located in the anterior part of the eye | fovea centralis |
| Help maintain the intraocular pressure; located on the anterior part of the eye | aqueous humor |
| area of greatest visual acuity | fovea centralis |
| Ear stones | Otoliths |
| Connects the middle ear with the nasopharynx | pharyngotympanic tube |
| Separates external auditory canal from the middle ear | tympanic membrane |
| Contains utricle and saccule | vestibule |
| Information from balance receptors goes directly to the | brain stem reflex centers |
| Which pairing of terms is incorrectly related | frequeny: loudness |
| In order, what stuctures does light pass through in the eye | Cornea, aqueous humor, lens, virteous |
| The boundary of the retina is called the | ora serrata |
| The rocks found in one's head are called | Otolithus |
