Test 2 Flashcards
dense hard tissue found in the shafts of long bones
compact bones
less dense tissue, found at the end of long bones
spongy/cancellous bones
muscle where movement is consciously controlled
skeletal/voluntary muscle
muscle where movements are not consciously controlled
smooth/involuntary muscle
muscle that is combination of smooth and skeletal muscles, involuntary contract
cardiac muscle
shapes the body, provides physical support and protection for organs. responsible for blood cell formation and storage of minerals
skeleton
crackling sound due to the grating of bones, may be heart on joint movement
crepitation
deposits of urate compounds in an around the joints of the extremeties
tophi
system that regulates and coordinates body activities and responses
nervous system
division of nervous system that processes and stores sensory information
central nervous system
division of nervous system that conducts information to and from the CNS
peripheral nervous system
what is in the central nervous system?
brain and spinal cord
what is in the peripheral nervous system?
sympathetic and parasympathetic
nerve cells that make up nerves, able to initiate or conduct electrochemical impulses
neurons
neuron that transmits impulses to the central nervous system
sensory/afferent neurons
sensory neuron coming from the skin, skeletal muscles, and joints
somatic
sensory neurons coming from internal organs
visceral
neurons that transmit impulses from the central nervous system to muscles and glands
efferent/motor neurons
connection between sensory and motor neurons and between themselves
interneurons
small space between the axon of one neuron and the dendrite of another neuron
synapse
body part that coordinates, controls, and regulates a number of life sustaining tasks
brain
body part that transmits electrochemical messages to and from the brain
spinal cord
protective layer that covers brain and spinal cord
meninges
responsible for fight or flight
sympathetic system
responsible for the calm and relaxation of the body in non stress situation
parasympathetic system
interuption of blood flow in cerebral vessel
ischemic stroke
rupture of a blood vessel
hemorrhagic stroke
what makes up the upper respiratory tract?
nose, pharynx, larynx, and upper trachea
what makes up the lower respiratory tract?
lower trachea, bronchi, bronchioles, alveoli, and lungs
cone shaped organs that sit in the chest cavity protected by ribs
lungs
what are lungs made up of?
millions of alveoli
membranes of the lungs
pleura
names of the two pleura
outer/parietal, inner/visceral
between both spaces that contains fluid secreted by the membranes
intrapleural space
sleep apnea where throat muscles relax
obstructive
sleep apnea where brain doesn’t send proper signals to the muscles that control breathing
central
sleep apnea that is a combination of obstructive and central
complex
Who is is sleep apnea more common in?
older men
Which conditions contribute to COPD
chronic bronchitis and pulmonary emphysema
severe irritation and inflammation of bronchial tubes
chronic bronchitis
gradual destruction of alveoli
pulmonary emphysema
asthmas in response to environmental irritant
extrinsic asthma
asthma without evidence of allergic response
intrinsic asthma
more common lung cancer that grows slower
non small cell lung cancer
less common lung cancer grows fast, metastasis
small cell lung cancer
