🗑
|
||||
| Tough connective tissue that joins muscles to bones | Tendons

| 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
🗑
