What is the primary difference between axial muscles and appendicular muscles?

Axial muscles are located along the head, neck and trunk and help with posture, head/neck and trunk movements. While appendicular muscles are located in the limbs and girdles and are responsible for limb movement and manipulation.

What’s the difference between general senses and special senses?

General senses refer to sensations distributed over large parts of the body, while special senses are localized and more complex: vision, hearing, taste, smell, and equilibrium

Describe in brief the main events of muscle contraction

Muscle contraction involves actin and myosin filaments sliding past each other, triggered by a nerve signal at the neuromuscular junction.

What is the role of the endocrine system in the body?

The endocrine system regulates body processes via hormones. Glands secrete hormones that travel through the bloodstream to target organs

What are the primary components of the cardiovascular system?

The cardiovascular system includes blood, the heart, and blood vessels. Together they circulate blood to transport nutrients and help regulate body temperature and pH.

What is the function of the lymphatic system?

The lymphatic system helps return excess tissue fluid to the bloodstream, transports lipids, and serves as part of the immune system

What’s the difference between innate immunity and adaptive immunity?

Innate immunity is non-specific, immediate defense while adaptive immunity is specific, slower to respond initially

What major structures are part of the respiratory tract?

The respiratory tract includes the upper and lower airways: nasal cavity, pharynx, larynx, trachea, bronchi, and the lungs

What ions are crucial for muscle contraction and nerve signaling?

Calcium is essential for muscle contraction while sodium and potassium are crucial for generating and propagating action potentials in neurons and muscle cells.

How do the heart and blood vessels work together to maintain blood pressure and circulation?

The heart pumps blood into arteries, generating pressure; arteries, veins, and capillaries regulate flow through resistance and vessel diameter
