Definitions Module 1
The study of the parts of the body and how they funcion and work together.
What is Physiology?
These organelles make most of the ATP in the cell
What are the mitochondria?
Ductless glands that secrete hormones into the bloodstream
What are Endocrine glands?
Networks of bone with many marrow-filled spaces surrounding the bone matrix forms this
What is Cancellous bone?
The type of neurons that transmit action potentials from the CNS to the effector organs
What are efferent neurons?
A group of tissues specialized for a particular function
What is an Organ?
What are Prophase, metaphase, anaphase and Telephase?
Spindle-shaped cells that form connective tissue proper
What are Fibroblasts?
This is the portion of the skeleton that supports and protects the head, neck, and trunk
What is the axial skeleton?
This neuron conducts action potentials from one neuron to another neuron within the CNS
What is an association neuron?
The study of tissues
What is Histology?
This is how small polar molecules, such as water, enter cells
What are channel proteins?
"Supporting" cells that provide structure or support for parenchymal cells
what are Stromal Cells?
A bone forming cell
what is an osteoblast?
What is Decussation?
The ability to let certain materials in or out while restricting others
What is selective permeability?
How larger molecules, such as carbohydrates, enter a cell.
what are carrier proteins
Cells that undergo mitosis regularly and quickly
what are Labile cells?
This is a large multinucleated cell that breaks down bone
What is an osteoclast?
Connections of neuron axons that allow the two hemispheres of the brain to communicate with one another
What are Commissures?
The process by which large molecules are taken into the cell.
What is Endocytosis?
A sodium ion (Na+) travels from inside the cell to outside the cell. The cell used ATP to make this happen. This is where the concentration of sodium ions is greater.
Where is the inside of the cell?
Mature cartilage cells
what are Chondrocytes?
The repeating unit of a myofibril
What is a sarcomere?
Receptors of the Skin
What are Cutaneous receptors?
