Nervous System
The basic functional cell of the nervous system.
What is a neuron?
This organelle is known as the cell's "powerhouse".
What is mitochondria?
This is the name for the outermost layer of the skin.
What is the epidermis?
This is the structural and functional unit of compact bone.
What is an osteon?
These two filaments slide past each other during muscle contraction.
What are actin and myosin?
This part of the brain is responsible for balance and coordination.
What is the cerebellum?
This type of transport requires no energy and moves molecules down a concentration gradient.
What is diffusion? (also acceptable: passive transport)
This protein is responsible for skin color.
What is melanin?
Name the bone cells that break down bone matrix to release calcium and other salts.
What are osteoclasts?
This neurotransmitter is released at the neuromuscular junction.
What is acetylcholine?
This cranial nerve is responsible for vision.
What is the optic nerve/CN II?
What is plasma membrane?
What are eccrine glands?
Name a bone that is not in the axial skeleton?
What is: radius/ulna/humerus/femur/fibula/tibia/tarsals/carpals, phalanges/pelvic bones/clavicles/scapula
This connective tissue surrounds skeletal muscle fascicles.
What is perimysium?
The change in membrane potential where the inside of the cell becomes more negative than the resting membrane potential.
What is hyperpolarization?
In this phase of the cell cycle, the chromosomes are at opposite ends of the cell prior to division.
What is telophase?
This layer of the epidermis contains stem cells that divide to replace keratinocytes.
What is stratum basale?
This portion of a long bone contains red bone marrow and tissue makes blood cells in children
What is the diaphysis?
What is calcium?
The function of this structure is to connect the cerebral hemispheres of the brain.
What is the corpus callosum?
During this phase of mitosis, chromosomes line up along the midline prior to separation.
What is metaphase?
This layer of skin contains blood vessels, hair follicles, and nerve endings.
What is the dermis?
This hormone increases blood calcium levels by stimulating bone resorption/breakdown.
What is parathyroid hormone?
Name the type of muscle contraction where tension increases but muscle length does not change.
What is isometric contraction?
