produces red and white blood cells, found mainly in spongy bone.
102
Medullary Cavity

stores fat and can convert to red marrow during extreme blood loss.
104
Periosteum

105
Why are there sutures in the skull?
allows brain growth, offer protection, and eventually fuse to form a solid structure as we age.
106
Sensory Neuron
(unipolar or bipolar)
transmit sensory information to the central nervous system.
107
Motor Neuron
(multipolar)
transmit signals from the central nervous system to muscles and glands.
108
Interneuron
(multipolar)
relay and process information between sensory and motor neurons within the central nervous system.
109
Unipolar
one process that splits into two branches, acting as both axon and dendrite.
110
Bipolar
one axon and one dendrite extending from opposite sides.
111
Multipolar
one axon and multiple dendrites.
112
Afferent Neuron
sensory neurons that carry impulses toward the central nervous system from sensory receptors.
113
Efferent Neuron
motor neurons that carry impulses away from the central nervous system to muscles or glands.
114
Does an interneuron have a direction of impulse?
yes, mpulses travel from sensory neurons to interneurons (processing and integration) and then from interneurons to motor neurons, which carry the response to muscles or glands.
115
What does the Endocrine System do?
is a collection of glands that produce and release hormones to regulate bodily functions.
116
What does the Endocrine glands produce?
they produce hormones that control various physiological processes, including insulin, adrenaline, estrogen, and cortisol.
117
Where are the Endocrine glands located?
they are located throughout the body, including the brain, neck, abdomen, and pelvis.
118
What happens to the neurons in multiple sclerosis?
the immune system attacks the myelin sheath around nerve fibers, disrupting nerve signal transmission.
119
What treatments are available for multiple sclerosis?
* disease-modifying therapies (DMTs)
* steroids for relapses
*symptom management like pain and muscle spasm medications are commonly used.
120
What is the prognosis of a patient with multiple sclerosis?
the prognosis varies :
* many people live normal lifespans with managed symptoms
* but disability can occur over time.
(early treatment helps improve outcomes.)
