Brain and Drugs
This part of the brain is primarily responsible for posture and balance
What is the cerebellum?
This system is primarily responsible for protection against bacterial attack and abrasion, but NOT blood cell formation.
What is the integumentary system?
This condition is characterized by loss of bone density
What is osteoporosis?
Blood from this chamber goes into the right ventricle
What is the right atrium?
The production of this substance in muscles is temporary and occurs due to a lack of oxygen.
What is lactic acid?
Heart rate, breathing, eating, and sleeping are controlled by this part of the brain
What is the brainstem?
Shivering and curling up with blankets are attempts to to do this to the body.
What is your raising its internal temperature?
The parietal bones of the skull are classified as this type of bone.
What are flat bones?
Your heart initially receives blood from this blood vessel
What is the vena cava?
For myosin heads to bind to actin, this molecule must be bonded to actin
What is calcium?
This drug causes extra dopamine release and blocks its reuptake
What is methamphetamine?
This response helps increase body temperature by reducing heat loss from the skin's surface.
What is blood vessel constriction?
This type of joint is characterized by the greatest degree of movement.
What is a synovial joint?
In which blood vessel is the blood most deoxygenated.
What is the pulmonary artery?
Rigor mortis occurs after death due to the lack of this molecule, causing actin and myosin to remain bound.
What is ATP?
This drug primarily blocks dopamine reuptake transporters.
What is cocaine?
This process cools the skin by sweating
What is evaporation
These cells are responsible for breaking down bone tissue
What are osteoclasts?
Blood pressure is highest in this major artery leaving the heart
What is the aorta?
Muscle cell contraction begins when this neurotransmitter travels across the synaptic gap and sodium rushes into the muscle cell.
What is acetylcholine (Ach)?
This depressant binds to the GABA receptor and inhibits the postsynaptic neuron
What is alcohol?
Aging skin wrinkles due to this loss in this characteristic of connective tissue
What is elasticity?
This type of fibrous joint in found between the skull bones
What is a suture?
These vessels supply and drain the heart muscle with oxygen and nutrients.
What are the coronary arteries and veins?
During muscle contraction, actin and myosin do this in relation to one another
What is slide on top of one another, neither shortens?
