Front

What bone is the olecranon process found on?

Back

The olecranon process is found on the ulna.

Front

What happens to a red blood cell when it is placed in distilled water?

Back

The red blood cell undergoes hemolysis.

Front

What type of connective tissue is found on the ends of long bones to reduce friction?

Back

Hyaline cartilage is the connective tissue found on the ends of long bones to reduce friction.

Front

What occurs during depolarization of the axon in a neuron?

Back

Depolarization occurs when sodium flows into the neuron.

Front

What charge does a sodium ion have after losing one electron?

Back

The sodium ion has a +1 charge.

Front

Define hemolysis.

Back

Hemolysis is the process where red blood cells burst due to an influx of water, often in a hypotonic solution.

Front

What is the function of hyaline cartilage in the skeletal system?

Back

Hyaline cartilage reduces friction between bones at joints and provides support.

Front

Explain the process of depolarization in neurons.

Back

Depolarization is the change in membrane potential that makes the inside of the neuron more positive, primarily due to sodium ions entering the cell.

Front

What is the significance of sodium ions in nerve impulse transmission?

Back

Sodium ions are crucial for generating action potentials, which are necessary for nerve impulse transmission.

Front

What is the role of the ulna in the human body?

Back

The ulna is one of the two long bones in the forearm, playing a key role in the structure and movement of the arm.
