100
the area of your eye that lets light into the eye and also helps focus light?
what is the cornea?
100
The fifth taste receptor, Japanese for "savory".
What is umami?
100
Active travel from place to place.
What is locomotion?
100
Mostly stored fat brought into the bone by the blood.
What is yellow bone marrow?
100
Strong fibrous connective tissues.
What are ligaments?
200
The smaller chamber in front of the lens.
What is aqueous humor?
200
Sensory neurons that line the upper portion of the nasal cavity and send impulses along their axons directly to the olfactory bulb of the brain.
What are olfactory receptors?
200
The five kinds of locomotion.
Swimming, hopping, walking and running, crawling, flying?
200
The specialized tissue that produces our blood cells.
What is red bone marrow?
200
The connection located where the humerus joins the pectoral girdle, enabling us to rotate our arms and legs and move them in several planes.
What are the Ball-and-socket joints?
300
As ligaments slacken, the elastic lens becomes thicker, allowing diverging light rays from a close object to be bent and focused.
What is accomodation
300
The kind of taste we sense from umami.
What is the amino acid, glutamate?
300
Consists of fluid held under pressure in a closed body compartment.
What is a hydrostatic skeleton?
300
Low bone mass from degeneration and structural deterioration of bone tissue.
What is osteoporosis?
300
Permit movement in a single place, just as the hinge on a door enables it to open and close.
What are Hinge joints?
400
The large chamber behind the lens, filled with a jellylike substance.
What is vitreous humor?
400
Receptors in our taste buds that detect molecules in solution, or in the nasal cavity that detect molecules in the air.
What are chemoreceptors?
400
A rigid external skeleton
What is an exoskeleton?
400
Keeps the bone flexible and non-brittle.
What is collagen?
400
The connection that enables us to rotate the forearm at the elbow.
What is pivot joint?
500
The outer surface of the human eyeball, which is a tough, whitish layer of connective tissue.
What is the sclera?
500
The type of cell surrounding sensory neurons.
What is an epithelial cell?
500
Consists of hard or leathery supporting elements situated among the soft tissues inside an animal body.
What is endoskeleton?
500
The minerals that form a bone matrix.
What are calcium and phosphate?
500
Discrete bundles of protein that include the contractile proteins actin and myosin.
What are myofibrils?
