Human Body Test #2 Review

-A type of cell that receives and sends messages from the body to the brain and back to the body. -Neurons are usually found in the brain and spinal cord (central nervous system).

-Your cerebrum is the largest part of your brain and is located at the top and front of your skull. Your cerebrum is the part of your brain that is responsible for motor activities, perception, understanding languages, vision, hearing, information, and memory.

-The Cerebellum is the small rounded section that is located at the back of your brain, where your brain connects to your spinal cord. Monitors muscle tone and position and coordinates new muscle movement.

-Thick white band of nerve fivers that connects the two halfs of the cerebrum and allows them to communicate and coordinate their activities. -It is located in the cerebrum.

-Divides a the cerebrum into right and left hemispheres. -Located in the brain.

-Neurons that connect to brain regions that allows for communication between sensory or motor neurons and the central nervous system. -Located in the brain and spinal cord.

-Are specialized cells in the nervous tissue that allow it to perform nervous system functions. They are like the “glue” that holds the nervous system together. -Located in the brain and spinal cord (central nervous system)

-Controls skeletal muscles and voluntary movement -Located in brain and spinal cord (central nervous system).

-Controls smooth and cardiac muscle in your organs and also several glands -Located throughout your head and body.

-Carries orders to all three types of muscle and to the body glands, and to tell them how to respond to new information. -Located in central nervous system.

-Provides sensory input for your nervous system. -Located in the post central gyrus of the perineal lobe.

-A women receives and injection of local anaesthetics into the epidural space so a woman can continue to participate actively in the birth without severe labor pains.

-Responsible for impulses that control heartbeat, breathing, and the muscle tone in blood vessels, which controls blood pressure. -Located in the lowest part of the brain and the lowest portion of the brainstem.

-Serve a very important purpose by increasing the surface area of the brain, yet allowing it to be “folded” into a smaller space. -Located in the cerebral cortex.

-Both brain and spinal cord, are surrounded by a series of protective membranes called meninges. The purpose is to cover over the delicate structures of the brain and spinal cord. They set up layers, cushioning, and shock absorbers.

Frontal lobes- are responsible for motor activities. Parietal lobes- are involved with body, perception, and understanding language. Occipital lobes- responsible for vision. Temporal lobes- are involved in hearing and the combination of sensory, information, and memory.

The section of the brain that is not visible form the exterior. It is responsible for controlling hormone levels, hunger and thirst, body temperature, sleep-wake cycles, and for coordinating the flow of information around the brain. -Located in the centre of the brain.

-The portion of the nervous system responsible for processing input from the environment. -Located in spinal cord and brain

-Combination of axon terminal and receiving cell (helps pass signals from one neuron to the next). -Located in the close connection between axon and dendrite

-Are used to send the signal from the neuron across the synapse to the next cell in line. -Located in the neuron

Neurons that clear the way for communication between neurons. -Located in neurons

An excitable cell carries a small electrical charge when stimulated. Because neurons are excitable cells, it makes sense that the way neurons send and receive signals is due to tiny electrical currents.

plasma- take nutrients, hormones, and proteins to the parts of the body that need it. erythrocytes (red blood cells)- carry oxygen leukocytes (while blood cells)- protect us from infection thrombocytes (platelets)- aid in clotting

-Antigens are like flags that indentify the blood cell. -Antibodies are like the cell body’s army that fight intruders (other blood types). When getting blood transfusion, you have to get blood that is your type or that you are able to receive or else the antibodies would fight the blood type that is not compatible with yours and will cause your blood to clot.
