| Question | Answer |
|---|---|
| What is the basic unit of life? | The cell |
| Name the four primary types of tissues in the human body. | Epithelial, connective, muscle, and nervous tissue. |
| What is homeostasis? | The process by which the body maintains a stable internal environment despite external changes. |
| Describe the function of the mitochondria. | Mitochondria are the powerhouses of the cell, responsible for producing ATP through cellular respiration. |
| What are the main components of the axial skeleton? | The skull, vertebral column, and rib cage |
| What is the role of red blood cells? | Red blood cells carry oxygen from the lungs to the body's tissues and transport carbon dioxide from the tissues back to the lungs. |
| What is the function of the skin? | The skin protects underlying tissues, regulates body temperature, and facilitates the sensation of touch. |
| What is the primary function of epithelial tissue? | To cover body surfaces, line cavities, and form glands. |
| What are the main layers of the skin? | Epidermis, dermis, and hypodermis (subcutaneous layer). |
| What is the primary function of the integumentary system? | To protect the body from external damage, regulate temperature, and provide sensory information. |
| What are the three types of muscle tissue? | Skeletal, cardiac, and smooth muscle. |
| What is the function of the sarcoplasmic reticulum in muscle cells? | It stores calcium ions that are released during muscle contraction. |
| What are axial muscles? | Axial muscles are those that are located along the axis of the body and include muscles of the head, neck, and trunk. |
| What is the primary function of axial muscles? | They support the head and trunk, maintain posture, and allow for movements such as flexion, extension, and rotation. |
| Name three major muscle groups in the axial skeleton. | Muscles of facial expression, muscles of mastication, and the muscles of the vertebral column. |
| What is the function of the rectus abdominis? | It flexes the vertebral column and helps compress the abdominal contents. |
| What are the muscles involved in respiration? | The diaphragm and the intercostal muscles. |
| What are appendicular muscles? | Appendicular muscles are those that are responsible for the movement of the limbs and the girdles (shoulder and pelvic). |
| What is the primary function of appendicular muscles? | They enable limb movements, such as walking, running, and grasping, and provide stability to the shoulder and pelvic girdles. |
| Name two major muscle groups in the appendicular skeleton. | Muscles of the shoulder (such as the deltoid) and muscles of the hip (such as the gluteus maximus). |
| What is the function of the biceps brachii? | The biceps brachii flexes the elbow and supinates the forearm. |
| Which muscle is the primary extensor of the knee? | The quadriceps femoris. |
