|---|---|
| What are Axial muscles? | Axial muscles are skeletal muscles located along the central axis of the body, including the head, neck, and trunk. |
| What are Appendicular muscles? | Appendicular muscles are the muscles that attach to the appendicular skeleton (limbs, pectoral girdle, and pelvic girdle) to enable movement, stabilization, and support. |
| What is the Orbicularis oculi? | The orbicularis oculi is a circular muscle that surrounds the eye, responsible for closing the eyelid and blinking. |
| What is the Orbicularis oris? | The orbicularis oris is a circular muscle around the lips, often called the "kissing muscle". |
| What is the Myelin sheath? | The myelin sheath is an insulating layer around the axon of a nerve cell that protects it and allows nerve signals to travel quickly and efficiently. |
| What makes up the Central Nervous System (CNS)? | The central nervous system (CNS) is made up of the brain and the spinal cord. |
| What makes up the Peripheral Nervous System (PNS)? | The peripheral nervous system (PNS) consists of all the nerves and ganglia outside of the brain and spinal cord. |
| What makes up the Autonomic Nervous System (ANS)? | The autonomic nervous system (ANS) consists of the sympathetic, parasympathetic, and enteric nervous systems. |
| What makes up the enteric nervous system (ENS)? | The enteric nervous system (ENS) is made up of neurons and glial cells in two main plexuses within the wall of the gastrointestinal (GI) tract: the myenteric (Auerbach's) plexus and the submucosal (Meissner's) plexus. |
| What 3 systems work together to coordinate all body systems? | The three primary systems that work together to coordinate all body functions are the Nervous System, the Endocrine System, and the Cardiovascular System. |
| What is the endocrine system? | The endocrine system is a network of glands and organs that use hormones to control and coordinate the body's metabolism, energy, reproduction, growth, and mood. |
| What is the most important gland in the endocrine system | The pituitary gland is the most important gland in the endocrine system because it is the "master gland," controlling many other glands like the thyroid, adrenal glands, and gonads. |
| What is the least understood gland in the endocrine system? | The pineal gland is often considered the least understood endocrine gland. |
| What makes up the Cardiovascular System? | The cardiovascular system consists of the heart, blood vessels (arteries, veins, and capillaries), and blood vessels. |
| Blood is what type of tissue? | Blood is a specialized type of connective tissue. |
| What is the primary muscle type of the heart? | The primary muscle type of the heart is cardiac muscle, also known as the myocardium. |
| What are the parts of the heart? | The main parts of the heart are the four chambers—the right atrium, right ventricle, left atrium, and left ventricle—and four valves: the tricuspid, pulmonary, mitral, and aortic valves. |
| What is the Lymphatic system? | The lymphatic system is a circulatory system made up of lymph vessels, which are much like blood vessels. |
| What is the Immune system? | The immune system is a complex network of cells, tissues, and organs that protects the body from disease. |
| How does the Lymphatic and Immune systems work together to keep you healthy? | The lymphatic and immune systems work together by using the lymphatic vessels to transport lymph, a fluid containing immune cells, to lymph nodes where it is filtered. |
| What is an Autoimmune disease? | An autoimmune disease is a condition where the body's immune system mistakenly attacks and destroys its own healthy cells and tissues. |
| What are 3 common diseases of the lymphatic system? | Three common diseases of the lymphatic system are lymphedema, lymphoma, and lymphadenopathy. |
| What is the Respiratory system? | The respiratory system is a network of organs and tissues that enables breathing, responsible for taking in oxygen and expelling carbon dioxide. |
| What organs make up the Respiratory System? | The respiratory system is made up of the nose, mouth, throat, voice box (larynx), windpipe (trachea), and lungs. |
| What are the most common diseases in the Respiratory system? | The most common diseases of the respiratory system are chronic obstructive pulmonary disease (COPD) and asthma, pneumonia, lung cancer and tuberculosis. |
| What is the Digestive system? | The digestive system is a group of organs that breaks down food into nutrients that the body can absorb and use for energy, growth, and repair. |
| What organs are in the Digestive System? | The digestive system includes the gastrointestinal (GI) tract (mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anus) and accessory organs like the salivary glands, liver, gallbladder, and pancreas. |
| What are 3 common diseases of the Digestive system? | Irritable Bowel Syndrome (IBS), Gastroesophageal Reflux Disease (GERD), and Peptic Ulcers. |
