CLASSIFY
Osteoclast
osteoblast
osteocytes
what are
-Osteoclasts are the cells that degrade bone
-cells that synthesize bone matrix
-Osteocytes are the longest living bone cells
explain sesnory input aand motor output
-sensory (afferent) signals picked up by sensory. receptors (carrie by nerve fibers to the PNS to the CNS
-Motor (efferent) signals are carried away from the CNS (innervate muscles and glands)
name the meninges superficial layer to deepest, and a breif discription
what is
1- Dura Mater = outermost, superficial; composed of fibrous tissue and thick
2- Arachnoid Mater = spider web like;
3- Pia Mater = deepest & delicate layer
—> protected by CSF (cerebral spinal fluid) found surrounding both the brain & spinal cord
What do I innervate?
-what is smooth muscle, cardiac muscle and glands
what are the outer levels from deepest level of connective tissue are

gray & white matter
White matter contains myelinated axons and gray matter contains cell bodies of neurons
im the integration center of the ANS
im the main limbic region or emotions
what is the hypothalmus and the amygdala
im a type of muscle that can be found in the surroundings of hollow organs
what is smooth muscle

how does information travel through the CNS. (hint dorsal root and ventral root)
all incoming info = going to the CNS enters thru the dorsal root (sensory neurons)
—> all info going from the CNS to target exits thru ventral root (motor neurons)
