Lofi hip hop A&P cards to study and stress to
microglia
Act as phagocytes, eating damaged cells and bacteria, act as the brains immune system
deep
Away from the body surface; more internal
proximal
Closer to the point of attachment
muscular tissue
Contracts and moves the various parts of the body.
transverse
Divides body into upper and lower parts
Oligdendrocytes
Forms myelin sheaths of axons in the CNS
dense regular connective tissue
Function: attaches muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction Location: tendons, most ligaments, aponeuroses
epithelial tissue
Tissue that covers outside of the body and lines organs and cavities.
Adipose Tissue
Tissue that stores fat.
medial
Toward the midline of the body
phospholid bilayer
a two-layered arrangement of phosphate and lipid molecules that form a cell membrane, the hydrophobic lipid ends facing inward and the hydrophilic phosphate ends facing outward.
distal
away from the point of attachment
hematopoietic stem cells
cell in the bone marrow that gives rise to all types of blood cells
carbohydrate
compound made up of carbon, hydrogen, and oxygen atoms; major source of energy for the human body
cuboidal
cube shaped cells
frontal
divides body into front and back
midline
divides body into left and right
sqaumous
flat cells
anterior
front of the body
ependymal cells
line cavities of the brain and spinal cord, circulate cerebrospinal fluid
areolar
loose connective tissue
lipid
macromolecule made mainly from carbon and hydrogen atoms; includes fats, oils, and waxes
protein
macromolecule that contains carbon, hydrogen, oxygen, and nitrogen; needed by the body for growth and repair
stratified epthelium
more than one layers of cells -able to withstand friction and can protect (built to change)
superficial
near the surface
electrolyte
produces ions and allows the body to function
connective tissue
provides support for your body and connects all its parts
simple epithelium
single layer of cells
satellite cells
surround neuron cell bodies within ganglia
columnar cells
tall and column shaped cells
posterior
toward the back
nervous tissue
A body tissue that carries electrical messages back and forth between the brain and every other part of the body.
cell membrane
A cell structure that controls which substances can enter or leave the cell.
cartilage
A connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together.
blood
A connective tissue with a fluid matrix called plasma in which red blood cells, white blood cells, and cell fragments called platelets are suspended.
skeletal muscle
A muscle that is attached to the bones of the skeleton and provides the force that moves the bones.
sagittal
A plane that divides the body into right and left portions.
superior
Higher on the body, nearer to the head
smooth muscle
Involuntary muscle found inside many internal organs of the body
cardiac muscle
Involuntary muscle tissue found only in the heart.
inferior
Lower on the body, farther from the head
Astrocytes
Provide structural and metabolic support for neurons.
schwann cells
Supporting cells of the peripheral nervous system responsible for the formation of myelin.
