8 Body Systems
Body Systems
| Question | Answer |
|---|---|
| Largest portion of the brain; responsible for voluntary activities of the body, intelligence, learning and judgement | Cerebrum |
| Second largest portion of the brain located at the back of the skull; coordinates balance and coordination | Cerebellum |
| Tough connective tissue that joins muscles to bones | Tendons |
| Connective tissue in a joint that holds bones together (holds bone to bone) | Ligament |
| Connective tissue that is softer and more flexible than bone and cushions the joints | Cartilage |
| Muscles that are attached to bones and control voluntary movement. They are striated. | Skeletal Muscles |
| Striated muscle in the heart that is not under voluntary control | Cardiac Muscle |
| Muscle tissue that lines internal organs and are not under voluntary control | Smooth Muscle |
| Place where two bones meet | Joint |
| System of bones, ligaments, tendons, and cartilage that supports the body, protects internal organs, produces red blood cells, stores minerals | Skeletal System |
| Where in the body are red blood cells made? | In the bones |
| Where in the body are minerals stored? | in the bones |
| What is the main job of red blood cells? | To carry oxygen to the cells |
| Are skeletal muscles voluntary or involuntary? | voluntary |
| are the muscles lining organs voluntary or involuntary? | involuntary |
| What two kinds of muscle are striated? | Cardiac muscle and skeletal muscle |
| What kind of muscle is smooth? | the kind of muscle that lines the inside of our organs |
| What is an effector? | A muscle. A stimulI "creates an effect" or contraction response of the muscle |
| The gap or space across which a neuron transfers an impulse over to another neuron | Synapse |
| Signals that cause nervous responses | Stimuli (Ex.a change in the environment, something hot that could burn, something loud or frightening, something sweet...) |
| A SENSORY cell that detects changes in the environment (stimuli) and begins a sensory response | Receptor ("Receives" the information from the environment.) |
| A nerve cell that conducts impulses | Neuron |
| Messages from receptors to the brain and back to the effectors | Impulses |
| Coordinates the body's response to external and internal changes in its environment; includes brain, nerves, and spinal cord | Nervous System |
| Cells that have receptors for specific hormones | Target cells |
| A system in the human body that helps maintain homeostasis. | Feedback Mechanism |
| The product of a system shuts down the system, such as pancreas and insulin | Feedback Inhibition |
| Structures in the male reproductive system that produce sperm | Testes |
| A disease in which the pancreas produces too little insulin so blood sugar is elevated | Diabetes |
| Structures in the female reproductive system that produce eggs | Ovaries |
| The gland responsible for maintaining blood sugar levels by secreting insulin or glucagon | Pancreas |
| Located on top of the kidneys, these two glands help the body prepare for and deal with stress (fight or flight) by secreting adrenaline | Adrenal Glands |
| This gland controls the body's metabolism by secreting thyroxin | Thyroid |
| Gland found at the base of the skull; secretes nine hormones that directly regulate many body functions and controls the actions of several other glands | Pituitary Gland |
| Controls the secretions of the pituitary gland | Hypothalamus |
| A chemical released by a gland into the bloodstream to affect specific target cells | Hormone |
| A gland that releases chemicals called hormones directly into the bloodstream | Endocrine Gland |
| Area of the brain that controls the functioning of internal organs | Medulla |
