Flashcards

Cerebral Lobes

The cerebrum is divided into four lobes: frontal, parietal, temporal, and occipital.

Brain Regions

Structures like the cerebrum, cerebellum, midbrain, pons, medulla oblongata, thalamus, and hypothalamus are key parts of the brain.

Spinal Cord Regions

The spinal cord contains anterior (ventral) horn, posterior (dorsal) horn, and lateral horn.

Sensory vs Motor in Spinal Cord

Each region of the spinal cord has sensory or motor functions related to sensations or movements.

What is the function of the frontal lobe?

The frontal lobe is responsible for higher-level cognitive functions like decision-making, planning, and personality.

Sensory Perception

The process of receiving and interpreting sensory information from the environment, like touch, sound, sight, smell, and taste.

Heart Chambers

The heart has four chambers: two atria (upper chambers) and two ventricles (lower chambers). The atria receive blood, and the ventricles pump blood out.

Heart Valves

Four valves regulate blood flow through the heart. The atrioventricular (AV) valves (mitral and tricuspid) control blood flow between atria and ventricles. The semilunar valves (aortic and pulmonary) control blood flow from ventricles to the aorta and pulmonary trunk.

What vessels drain into the atria?

The superior and inferior vena cava drain into the right atrium, while the pulmonary veins drain into the left atrium.

What vessels receive blood from the ventricles?

The right ventricle pumps blood to the pulmonary trunk, and the left ventricle pumps blood to the aorta.

Aorta

The aorta is the largest artery in the body. It carries oxygenated blood from the left ventricle to all parts of the body.

What are the major veins?

Key veins include the superior and inferior vena cava (returning blood to the heart), pulmonary veins (returning oxygenated blood from the lungs), and femoral veins (in the legs).
