Body Directions
A patient is described as having “no pulse.” The prefix that means “not” or “without” is this.
a-
This body system is your outer protection team: skin, hair, nails, and glands.
Integumentary system
The adult human skeleton contains this many bones.
206
A muscle cell has a more athletic name — it is also called this.
Muscle Fiber
Hormones are not texts, emails, or Snapchats — they are this type of body messenger.
Chemical Messengers
This tiny kidney unit does the filtering work and helps form urine.
Nephron
If a doctor says something involves an “arthr-” problem, this body structure is probably involved.
Joint
These two main skin layers work together: one on the outside and one underneath with blood vessels and nerves.
Epidermis and Dermis
Bone may seem rock-like, but it is actually classified as this type of tissue.
Connective Tissue
This strong connective tissue attaches a muscle to a bone so movement can happen.
Tendon
These two pancreatic hormones work like opposite teammates to help regulate blood sugar.
Insulin and Glucagon
These two tubes are the “urine highways” from the kidneys to the bladder.
Ureters
A lab report mentions an erythrocyte. The suffix “-cyte” tells you it is this.
This pigment is like your skin’s built-in sunscreen because it helps protect against UV rays.
Melanin
On a long bone, this is the long shaft area between the two ends.
Diaphysis
This tiny repeating unit is where muscle contraction actually happens.
Sarcomere
This blood vessel type is the “exit road” that carries blood away from the heart.
Artery
This enzyme in saliva starts breaking down starch before food even reaches the stomach.
Salivary Amylase
Your ears are located in this direction compared to your nose.
Lateral
These sweat glands are the MVPs of cooling you down when your body overheats.
Eccrine sweat glands
These “builder” bone cells make osteoid and help form new bone tissue.
Osteoblasts
During a muscle contraction, this thick myofilament does the pulling.
Myosin
This powerful heart chamber sends oxygen-rich blood into the aorta for delivery to the body.
Left Ventricle
Before pathogens get to the fancy immune responses, they first have to get past this first line of defense.
Surface Barriers
A magician “cuts” the body into left and right sections. This is the anatomical plane being used.
Sagittal Plane
This skin layer does not have its own blood vessels, so it depends on nearby capillaries for nutrients.
Epidermis
This group of vertebrae attaches to the ribs.
Thoracic vertebrae
This is the “meeting place” where a motor neuron communicates with a muscle fiber.
Neuromuscular Junction
These tiny air sacs are where oxygen enters the blood and carbon dioxide leaves it.
Alveoli
These lymphocytes handle cell-mediated immunity instead of making antibodies.
T cells
