2. true or false, explain why the state is false : Bipolar neurons have a central cell body with two extensions: true
- List the phases of an action potential in order: 1. resting potential
- depolarization 3.repolarizarion 4.resting condition
- true or false , if false explain why the statement is false: the central nervous system consists of the brain and spinal cord: true
- name and describe what is occurring in the neurocell membrane in section 2 of the diagram. include the charge of the membrane during this phase: de-
- the neuron pictured below, is best described as: multipolar
privation, sodium gates are opened and the sodium floods into the axon admits the depolarization of the action potential, causing the charge voltage to go from 0 to + mV
6. This part of a reflex is inside the CNS, made up of one or more synapses.: - integration center
- match the following lobes of the brain with the correct function: temporal - contains sensory areas for hearing and smelling frontal- contain higher levels ex.. pariteal - receives sensory info from body receptors occipital - interprets visual input
- which of the following structures of the spinal cord contains the cell bodies of afferent neurons: dorsal root ganglion
- what is true about the flexor withdrawl reflex: A&d (IT DOES NOT INVOLVE INTERNEURONS & THE EFFECT OF THE REFLEX IS TO CREATE A CO-CON- TRACTION OF 2 MUSCLES 10. Label the nerves (A-C) in the figure below:
- which of the following is most likely a symptom of ASL: impaired ability to swallow
- describe the function of the parasympathetic nervous system: aka the housekeeper system because it promotes all of the internal responses in the relaxed state. Parasympathetic stimulation causes the pupil of the eye to get smaller and aids the lenses of the eyes to focus on close items. it helps with the digestion of food and also helps with the beating of the heart and slowing it
- which of the following visual conditions is caused by damage to the abducens nerve?: diplopia
- what is the purpose of the blood brain barrier? describe its maintenance from a cellular level: it is a diffusion barrier that helps in the prevention of unneeded materials that attack the CNS by keeping the brain and spinal cord away from the general blood bank.It is composed of the gilal cells astrocytes and its pertinent for regulation to be able to keep a homestatis which aids in protecting the neurons
- a pt is unable to extend his left wrist or fingers. what never is most likely
damaged ?: radial nerve
- explain the main steps in the process of hearing: 1.) sound waves are funneled through the external auditory Canal which causes the eardrum to vibrate
- the vibrations go into the ossicles and push against the fluids inside the cochlear duct. the movement of the fluid causes the stereocilla in the organ of court to move as well.the neurons are stimulated to send impulses through the cochlear nerve to the primary auditory cortex of the temp lobe
- which cell serves as stem cells in the gustatory system that divide and differentiate into new supporting cells then form new gustatory cells: basal cells
- fill in the blanks: the two upper receiving chambers of the heartier called the , while the two lower pumping chambers are called the: ratio , ventricles
- which of the following is not a type of granulocyte: b-cells
- describe how memories are stored and retrieved in the brain. include a spe- cific brain region.: the amygala and the involvement of the limbic system explains why emotionally charged events and occurrences cause our most vivid memories.
ndicated by
- a bolus is formed by the : tongue
- T/F: The tongue contains nociceptors and thermoreceptors in addition to chemoreceptors.: true
- what's the purpose of the fossa avails in a fetus: the fossa marks the place of opening between the atria which is present in all growing fetuses. it permits blood to flow directly Erin the right t the left atrium,. the fossa closes during birth so the lungs can gain access to oxygen once the baby is born
- Name the vessel in the figure below: (highlighted in blue, also i the arrow): circumflex branch
3.)cochlea 4.)tympanic membrane 5.)incus
hatic duct
- use the figure below to answer the following : which part of the medical equipment (b-f) is squeezed to inflate A: F. the bulb
- oxygenated blood is pumped from the heart through the to the rest of the body .: left, systemic circuit
- you are reviewing your pts results from an egg. the findings indicate a problem with ventricular depolarization. where should you look on the keg to find this abnormal rhythm: qrs complex
- a pt is suspected to have peripheral edema due t heart failure. which side of the heart would be in failure? explain: the right side of the heart because right sided heart disease usually causes the backup of fluids in the limbs of the body
- name the lymphatic vessel below highlighted in blue: right lymp
gure below- the uterus in the longest
lactic shock due to a dramatic decrease in blood pressure and closed respiratory passageways
- match the cell with its best description. select all that apply: has the greatest phagocytosis properties of the white blood cells: macrophage and monocyte
- label the regions of the reproductive system below (a-c): a. prepuce b. urethral orifice c. vestibule
- the connects the seminal vesicle with the urethra to allow sperm to exit the body: ejactulary duct
- which of the following is true concerning human cells?: gamete cells are haploid cells 39. name ad discuss the stage of labor that best describes the fi : the dilation of the cervix, which has to reach 10cm and once it does, contracts and the baby's head is pushed against the cervix dilating it
stage of labor
- based strictly on anatomical structural differences, are males or females more likely to get a UTI? why or why not: females because the female urethra is shorter and located near the anus which causes for poornhygienve after bowel movements. not wiping correctly can cause the feca bacteria to inhabit the urethra and trade within the urinary system and cause a UTI
- what causes an extremely high blood pressure in the glomeluar capillar- ies: the difference in diameter causes very high bp which results in the water and solutes to exit the blood and make their a inside of the glomeluar capillaries which are known to filtrate
- which of the following is false concerning the cardiovascular barorecep- tors: if blood volume rises, they cause constriction of the afferent arterioles
- a person is hyperventilating. this falls under what control mechanism. explain what hyperventilation accomplishes: it falls under respiratory control because hyperventilating is an escalation in respiratory rate and aids in getting rid
indicated by
the kidneys to other pertinent organs, when the nervous system takes over control the afferent arteriole diameter becomes smaller
- list the 4 parts of the human brain: cerebral hemispheres, diencephalon, brain stem, cerebellum
- list and describe the 3 meninges of the human brain: 1. the leathery dura mater which is composed of the double layered outer meninx
- the middle arachnoid meninx which is loose layer separated from dura mater by the subdural space
- the inner Pia meninx is composed of connective tissue and is tightly attached to the brain
- What blood cells contain hemoglobin?: red blood cells
- P waves represent what?: atrial depolarization
- Define systole: Contraction of the heart
- what is muscle tone and how is it maintained: Muscle tone is the degree at which muscles remain partially contracted while at rest. Muscle tone is continuously
monitored and maintained by the cerebellum to keep bones and joints in place.
- Name the vessel in the figure below: (highlighted in blue, also the arrow): posterior interventricular artery
- a pt is suspected to have peripheral edema due to heart failure. which side of the heart would be in failure? explain: the right side of the heart be in failure, if the right side of the heart cannot pump blood into the heart efficiently, blood and fluid will back up into the veins, causing swelling in body tissues.
- name the lymphatic duct highlighted in blue below: left lymphatic duct
- interferons inhibit what type of infection agent: virus
- a pt is admitted to the ER with hives and difficulty breathing. what is most likely happening: anaphylaxis
- match cell with best description: performs phagocytosis: neutrophil, eosinophil,basophil,macrophage and monocyte
- the connects the seminal vesicle with the urethra to allow sperm to exit
- describe the difference between the 2 types of nephrons: 1. cortical nephrons which are in the cortex region of the kidney , with the exception of the loop of henle which extend to the medulla
- the remaining nephrons, aka the juxtamedullary nephrons, pass deeply into the medulla because ofbtheir location and their longer loops of henle
