skin
layers of keratinocytes
what is nervous tissue
cells specialized for communitcation via electrical/ chemical signals
detect stimuli and transmit information
support and protect neuronsbrain and spinal cord
what is gray matter and what does it contain
houses the cell bodies of motor neurons and interneurons
anterior horn:cell bodies of somatic motor neurons
posterior horn: axons of sensory nerves
what is kyphosis
posterior curvature of the spine in the thoraic region
hunchback
what is part of the atlanton-axial joint
oblique captitis inferior
oblique capitis superior
rectus capitis posterior major
what is straum bisale?
attached to basement membrane
stem cells>diferentiate to keratinocytes
melanocytes=produce melanin
merkel cells=respond to tactile stimulation
what does aprocine do
produce hormonal secretion
what is white matter and what does it contain
houses the myelinated axons
funiculi: a column of white matter, made up of coluns of axons
fasciculi: multiple fasculi (tracks)-bundles of axons with shared functions
what is lordosis
increase of lumbar curvature
sway back
what are the medial rotators of the gluteal region
gluteus minimus, gluteus medius
what is the epithelial tissue
layers of closely packed cellscovers organ surface or form glands
protection, secretion, absorption
what does a sebacaeous gland do
generates oil
what are ascending and descending tracts
ascending tracts: carry sensory information up (procioperception)
descending tracts: carry motor information down
what is part of the erector spinae group? and function
illocostalis, logissimus, spinalis
bi-extension of the vertebreal column
what are the lateral rotators of the gluteal regions?
gluteus maximus, piriformis, inferior gemellus, superior gemellus, quadratus femoris, obturator internus
what is connective tissue
cells that occupy less space than the extracellular material
connects, sepaartes, supports all other types of tissue in the body
support, protect, bind together organs
tendons, ligaments
what does a rector pilli do
causes hair to stand on hand
what are dorsal and ventral roots?
dorsal=connects dorsal (posterior) horn
carry sensory information to the spinal cord
ventral= connects ventral horn
carry motor information from the spinal cord to the muscles and glands
what is part of transveralis group, function and vertebraes it spans?
rotatores, spans 1-2 vertebrae
multifudus, spans 3-4 vertebrae
semispinalis, spans 5-6 vertebrae
rotation of the vertebreal column on the opposite side
lateral extension of the vertebreal column and head
what does the superior/inferior gluteal nerve do?
superior: intervates gluteus med, minimus, and tensor fascie latae
inferior: supplie gluteus maximus
what is muscle tissue
specialized cells contract when stimulated
skeletal, cardiac, smooth
moves skelten, organ walls
what is the classifciation of tissue
1. # of cells
2. cell shape
what is scoliosis
lateral curvature of the spine
what is part of the atlanto-occipital joint?
oblique capitis superior
rectus capitis posterior minor
rectus capitus posterior major
what does the sciatic nerve do
innervate the leg but has nothing to do with the gluteal region
