|---|---|
| What is the primary function of the axial muscles? | The primary function of the axial muscles is to support and move the head, neck, and trunk, maintaining posture and balance. |
| Name two muscles that are part of the appendicular muscle group. | Two muscles that are part of the appendicular muscle group are the biceps brachii and the quadriceps femoris. |
| What are the main types of glial cells in the central nervous system? | The main types of glial cells in the central nervous system are astrocytes, oligodendrocytes, microglia, and ependymal cells. |
| Describe the function of a neuron. | The function of a neuron is to transmit electrical signals (nerve impulses) throughout the body to communicate information. |
| What are the main components of the central nervous system (CNS)? | The main components of the central nervous system are the brain and spinal cord. |
| Explain the primary functions of the autonomic nervous system (ANS). | The primary functions of the autonomic nervous system are to regulate involuntary physiological processes, including heart rate, blood pressure, respiration, and digestion. |
| How do sensory receptors transmit signals to the brain? | Sensory receptors transmit signals to the brain by converting external stimuli into electrical impulses that travel through nerves to the central nervous system. |
| What is the role of the pituitary gland in the endocrine system? | The pituitary gland, often called the "master gland," regulates the function of other endocrine glands and releases hormones that control growth, metabolism, and reproduction. |
| Describe the pathway of blood through the heart. | The pathway of blood through the heart is as follows: deoxygenated blood enters the right atrium, flows into the right ventricle, is pumped to the lungs via the pulmonary arteries, returns oxygenated to the left atrium, enters the left ventricle, and is t |
| What are the components of blood and their primary functions? | The components of blood are red blood cells (carry oxygen), white blood cells (fight infection), platelets (assist in clotting), and plasma (the liquid part that carries nutrients, hormones, and waste products). |
| What is the role of the lymphatic system in immune function? | The role of the lymphatic system in immune function is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body, and to filter out harmful substances. |
| Identify two types of cells involved in the immune response. | Two types of cells involved in the immune response are T lymphocytes (T cells) and B lymphocytes (B cells). |
| Explain the process of gas exchange in the alveoli. | Gas exchange in the alveoli occurs when oxygen from inhaled air diffuses through the walls of the alveoli and into the surrounding capillaries, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. |
| What muscle is primarily responsible for facilitating breathing? | The diaphragm is the primary muscle responsible for facilitating breathing by contracting and relaxing to change the pressure in the thoracic cavity. |
