Anatomy Basics
This plane divides the body into anterior and posterior portions.
Frontal Plane
The adult human skeleton normally contains this many bones.
206
These two proteins interact to cause muscle contraction.
Actin and Myosin
This pigment helps protect the skin from UV radiation.
Melanin
The body's ability to maintain a relatively stable internal environment.
Homeostasis
The organizational level that comes directly after tissue.
Organ
This is where blood cells are produced.
Red bone marrow
During a bicep curl, the triceps acts as this type of muscle relative to the biceps.
Antagonist
Name two functions of the integumentary system.
Protection
Temperature Regulation
Sensation
Vitamin D production
Excretion
What are 3 examples of how homeostasis is regulated in the body?
Fluid Balance
Body Temperature
Blood Sugar
If your nose is above your mouth, your nose is ______ to your mouth.
Superior
Name three functions of the skeletal system.
Structure/support, movement, mineral storage, protection, and hematopoiesis.
This muscle group is located on the front of the thigh.
Quadriceps
This process allows the skin to help regulate body temperature when you become hot.
sweating
What is the purpose of the negative feedback Loop?
To help the body return towards normal conditions
Stop
This type of tissue lines internal and external body surfaces.
Epithelial Tissue
This bone is located on the lateral side of the lower leg.
Fibula
Sacromere
Why are some areas of your skin more sensitive to touch than others?
ifferent areas have different densities/distributions of sensory receptors.
In this type of feedback loop, the response amplifies or increases the original stimulus.
Positive Feedback Loop
Put these in order from least complex to most complex: cell, organ, tissue, organ system, organism.
Cell → Tissue → Organ → Organ System → Organism
What happens to the growth plates when a person stops growing
Growth plates ossify
How do agonist and antagonist muscles work together to produce movement
Opposing muscle groups; when one contracts the opposing muscle relaxes
How does differences in melanin contribute to the variation in human skin color
Amount/type of melanin produced contribute to differences
Your body temperature drops when you go outside on a cold winter day. What response would help bring your temperature back toward normal?
Shivering
