What are the three types of muscle?
Skeletal muscle, smooth muscle, cardiac muscle
What is included in the nervous system?
The brain, spinal cord, and the nerves.
How does the mitochondria produce ATP?
Through cellular respiration.
Epithelial tissue.
What are the ends of the long bone called?
Epiphyses.
True or False. Myosin are thick filaments and actin are thin filaments.
True.
What are neurons?
They are masses of nerve cells that transmit information.
True or False. Molecules move from areas of low concentration to high concentration.
False, molecules move from areas of high concentration to low concentration.
What are the three types of cells in connective tissue and what are their functions?
1. Mast cells (prevents clots)
2. Macrophages (consumers)
3. Fibroblasts (produce fibers)
What are the four types of diarthrotic joints?
Saddle, Hinge, Pivot, and Ball and Socket joints.
What is the neuromuscular junction?
Where a nerve and muscle fiber come together.
What is the difference between Oligodendrocytes and Scwhann cells?
Oligodendrocytes are found in the CNS (Central Nervous System) and Schwann cells are found in the PNS (Peripheral Nervous System).
How does secretion happen during exocytosis?
A vesicle containing the molecules that need to be released fuses with the cell membrane and the contents of the vesicle are released.
True or False. In nerve tissue, axons receive messages from other neurons and dendrites send messages to other cells.
False. Axons send messages to other cells and dendrites receive messages from other neurons.
What pairs of ribs make up the thoracic cage? (Please include the names of the pairs and which ribs they're correlated to)
True Ribs = First seven
False Ribs = Next 3 pairs
Floating Ribs = Last two pairs
Muscle contraction occurs as the thin filament slides past the thick filaments.
True or False. Dopamine is responsible for pain reduction and Endorphins are responsible for happiness.
False. Dopamine is responsible for happiness and endorphins are responsible for pain reduction.
What are the 5 steps of telophase?
Chromosomes disappear
Nuclear membrane reforms
Nucleoli reappears
Spindle disappears
Centrioles duplicate
What causes epidermolysis bullosa?
Faults in the protein (collagen) that act as the glue which holds our layers of skin together.
What is the importance of the foramen magnum?
The foramen magnum serves as a passage of the central nervous system, connecting the brain with the spinal cord.
How does tetanus affect the body?
Tetanus causes cholinesterase to not break down the acetylcholine in the synapse. This results in a person's muscles contracting and not relaxing.
What is the function of the Wernicke's area, which is in the temporal lobe (on the left hemisphere)?
The Wernicke's area helps with understanding sentences.
