This is the outermost layer of the skin
what is the epidermis?
This muscle is known as the “calf muscle” and helps you stand on your tiptoes.
What is the gastrocnemius?
This part of the nervous system includes the brain and spinal cord.
what is the central nervous system? (CNS)
This bone is also known as the kneecap.
What is the patella?
This chamber of the heart pumps oxygenated blood to the entire body.
what os the left ventricle
This type of sweat gland is responsible for producing sweat that helps cool the body.
what is the eccrine gland?
This large chest muscle is responsible for flexing and adducting the arm.
What is the pectoralis major?
These cells support, protect, and nourish neurons but do not send electrical signals.
What are neuroglia (glial cells)?
These are the two bones of the lower arm, one located on the thumb side and the other on the pinky side.
What are the radius and ulna?
These two chambers receive blood returning to the heart.
What are the atria?
This pigment gives skin its color and helps protect against UV radiation.
What is melanin?
This powerful chewing muscle elevates the mandible
What is the masseter?
This part of a neuron receives incoming signals from other neurons.
What are dendrites?
This part of a long bone is the shaft and contains the medullary cavity.
What is the diaphysis?
This valve prevents backflow of blood from the left ventricle into the left atrium.
What is the bicuspid (mitral) valve?
This deeper layer of the skin contains blood vessels, nerves, and hair follicles.
what is dermis
This muscle runs from the sternum and clavicle to the mastoid process and is responsible for rotating and flexing the neck.
what is the sternocleidomastoid
This division of the autonomic nervous system (ANS) is responsible for the “fight or flight” response.
What is the sympathetic nervous system?
These small spaces within compact bone house osteocytes.
What are lacunae?
This layer of the heart wall is composed of cardiac muscle tissue and is responsible for the heart’s contractions.
What is the myocardium?
These are the five layers of the epidermis, listed from deepest to most superficial.
What are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum?
These are the three hamstring muscles located on the posterior thigh. (from superficial to deep)
What are the biceps femoris, semitendinosus, and semimembranosus?
These are the three meninges that protect the brain and spinal cord, listed from outermost to innermost.
What are the dura mater, arachnoid mater, and pia mater?
These tiny channels connect lacunae to each other and allow nutrients and waste to travel between osteocytes.
What are canaliculi?
These muscles anchor the chordae tendineae and contract during ventricular systole to prevent the AV valves from prolapsing into the atria.
What are the papillary muscles?
