Cellular Tetris
This basic type of muscle tissue is voluntary and is responsible for moving your body.
What is skeletal muscle?
This is the outermost layer of the skin, acting as a barrier to protect the body from the environment.
What is the epidermis?
This membrane-bound organelle packages, tags, modifies, and transports proteins. It also plays a key role in preparing cellular products for secretion.
What is the Golgi apparatus?
Jake is standing up straight with his palms facing forward, what position is he in?
What is Anatomical Position?
In response to high body temperature, this homeostatic process increases sweat production and dilates blood vessels to release heat.
What is thermoregulation?
This dense connective tissue type allows tendons and ligaments to stretch in only one direction due to its parallel arrangement of collagen fibers.
What is dense regular?
The subcutaneous layer, also known as the hypodermis, is primarily composed of this type of tissue, which insulates and cushions the body.
What is adipose tissue?
When a cell is placed in a hypertonic solution, water moves out of the cell. Identify the cellular process responsible for this movement.
What is osmosis?
Jake falls backward on ice while ice skating and when he opens his eyes he can see the sky, what position is he in?
What is Supine Position?
After eating a meal, your blood sugar levels rise. In response, the pancreas releases insulin, which allows cells to absorb glucose and lowers blood sugar back to normal levels. What type of homeostatic mechanism is this?
What is negative feedback?
In an experiment, cells are observed to undergo cell death, triggered by enzymes that dismantle the cellular components without causing inflammation. What is this process?
What is Apoptosis?
This basic type of muscle tissue are your arrector pili muscles, they are responsible for moving your hairs.
What is smooth muscle?
A large particle has been "eaten" by a cell through the process of engulfment, forming a vacuole around the particle, what has just occurred?
What is phagocytosis?
Jake has both his right arm and his right leg broken in a car crash, how would you describe these breakages in relation to each other?
What is Ipsilateral?
After an injury, an overproduction of collagen during the healing process can lead to the formation of a raised, thickened scar that extends beyond the original wound. What is this type of scar called?
What is a keloid?
These specialized structures in cardiac muscle tissue connect individual heart muscle cells, facilitating both electrical signal transmission and mechanical contraction by allowing ions to pass rapidly between cells. What are these structures called?
What are intercalated discs?
This protein, found exclusively in the stratum lucidum, forms tight junctions between cells, adding an extra layer of protection in areas like the palms and soles. What is this protein?
What is eleidin?
In enzyme regulation, what is the process called where a molecule binds to an enzyme at a site other than the active site, altering the enzyme's activity?
What is allosteric inhibition?
Jake had one of his ribs broken in a basketball game, and a piece of bone punctured his right lung. This central cavity contains all of the other organs in the thoracic cavity except the lungs.
What is the mediastinum cavity?
Following a blood vessel injury, the coagulation cascade is activated, leading to the conversion of fibrinogen into this insoluble protein that forms a mesh to stabilize the clot and stop bleeding. What is this protein called?
What is fibrin?
During tissue analysis of a chronic wound, you observe a high level of Irregular cell death, alongside disorganized, excessive scar tissue formation. This condition is associated with the rupture of cell membranes, resulting in the complete destruction of cells and their components. What is this form of cell death called, and what process is responsible for the excessive tissue growth?
What are necrosis and fibrosis?
In this brief transition phase of the hair growth cycle, the hair follicle undergoes structural changes as it detaches from the nourishing blood supply and prepares to enter a resting state. This phase marks the end of active growth and typically lasts around 10 days. What is this phase called?
What is catagen?
In certain types of cell-to-cell communication, channels are formed that allow ions and small molecules to pass directly between adjacent cells. What are these protein complexes called that form these channels, enabling this direct communication?
What are connexons?
After falling down a flight of stairs, Jack experiences severe pain in his right lumbar region, and imaging reveals a fracture in his right iliac crest. Additionally, his right arm and leg show limited mobility due to damage to ipsilateral muscles. Name the three organ systems that are directly impacted in this scenario.
What are the nervous system, skeletal system, and muscular system?
When exposed to sunlight, the skin begins the production of Vitamin D. It is then converted in the liver to this form, which is a precursor to the active hormone that helps regulate calcium absorption in the intestines. What is this form of Vitamin D called?
What is calcidiol?
