tissues
The body contains four main types of tissues. These are the?
epithelial tissue
connective tissue
muscle tissue
nervous tissue
A tissue consists of packed cells that form surface covering, such as the layer of your skin and the lining of your nose. This covers and protects inner tissues.
epithelial tissue
A tissue that joins, supports, protects, insulates, nourishes, and cushions the body organs.
connective tissue
A tissue that keeps organs, such as the stomach and heart from falling apart.
connective tissue
Sample of connective tisue?
bones and ligaments
Is made up of cells that can contract and relax to produce movement.
muscle tissue
Is a tissue that helps move the parts of your body?
muscle tissue
A tissue that sends electrical signals to your body?
nervous tissue
A tissue that is found in your brain, nerves and sense organs.

A system that supports and protects the internal organs; allows movement.
Skeletal system
A system that moves that body and its parts.
Muscular system
A system that delivers nutrients to body cells and carries away wastes from the cells.
Circulatory system
A system that receives and transmits messages in the body.
Nervous system
A system that moves oxygen into the blood and carbon dioxide out of the blood.
Respiratory system
A system that breaks down food into simple nutrients that the body cells can use.
Digestive system
A system that removes waste products from the body.
Excretory system
Is the primary control center of your body. It is able to receive, integrate, store, and retrieve information.
Brain

Brain
The brain is protected by the cranium or skull. It is composed of cells called _____
neurons
Neurons carry electrical signals called _______
impulses
The _____ is connected to the spinal cord, which helps nerves send neurons to different parts of the body.
brain
The brain has three connected parts:
cerebrum, the cerebellum and the medulla
Is the largest part of the brain, which controls voluntary movements and detects touch, light, sound, odor, taste, pain, heat, and cold.
cerebrum
Receives sensory impulses from the muscles and joints.
cerebellum
Connects the brain to the spinal cord.
medulla
The cerebrum is the large rounded area of the brain divided into _____ and _____.
right hemispheres and left hemispheres
The left side of the brain controls ______
language, speech, and critical thinking
The right side of the brain is important in ______
performing arts and music
At the rear of the brain is the ______________.
cerebellum
It controls balance, posture, and coordination. It sends impulses to different skeletal muscles to make them contract, keeping you upright.
cerebellum
The part of your brain that connects to your spinal cord is called _______
medulla
It controls your blood pressure, heart rate, involuntary breathing, and some other involuntary activities
medulla
Is a bundle of nerve tissues extending from the brain through the backbone.
spinal cord
True or False: Messages from the brain and the body run up and down the spinal cord.
True
Is a brain injury from a hard hit resulting in a temporary disturbance in brain function, sometimes with unconsciousness and confusion.
concussion
Is an abnormal increase of the cerebrospinal fluid inside the skull, making the brain enlarged. Usually, the fluid is not circulating in the brain properly.
hydrocephalus
True or False: Any sensory information to and from the brain may not be able to travel if the spinal cord is injured.
