Terms in this set (35)
The body's ability to maintain all functions at a constant stable point
Going farther and farther from homeostasis.
Having abnormal levels in the body and the body being able to return it to normal levels.
Ex. Eating sugary lunch and having high blood sugar but hours later your blood returns to normal levels
Standing up straight, facing forward and palms out. It's universal and it's easier to describe body locations
Three functions of connective tissue
Protects body tissue, support body tissue, and binds tissues together
Protects the heart and lungs
Ex. Thoracic cage
Forms supporting structures of the larynx
Dense connective tissue
Forms tendons and ligaments
Ex. Biceps brachii use tendons to connect to the forearm.
3 important functions of epithelial tissue
Protection, filtration, secretion.
Stratified squamous epithelial
Thick epithelium that prevents lower, more delicate tissues from being destroyed from body processes
Ex. Mouth, outer portion of the skin.
Simple squamous epithelium
Filters oxygen and carbon dioxide from body tissues
Secretes mucous, hormones, sweat and oil
Ex. Endocrine and exocrine glands
3 appendages from the integumentary system
Sebaceous glands, eccrine glands, hair
Produce oil and prevent bacterial infections, keep skin soft, and prevents hair from "breaking"
Produce sweat and reduce heat through evaporation
Guards the head against bumps and the eyes against particles, keeps foreign particles from entering the body
1st degree burn
Only epidermis damaged
Area becomes red and painfully
2nd degree burn
Dermis is damaged
Skin is red and painfully, blisters appear. Enough of the dermis to be repaired.
Destroyed all the way down to the hypodermis
Burned area appears charred. Nerves destroyed.
Two types of cells that affect bone growth
Creates or builds bone. Stores calcium.
Breaks down or destroys bone. This will release calcium.
Two preventative measures of Osteoporosis
Weight bearing exercise to increase bone density
Consuming vitamin d and calcium
3 functions of the skeletal system
Support, protection, movement.
An injury to the femur preventing the ability to walk
An injury to the skull can lead to swelling of the brain and cause damage
If a tendon or ligament snaps then that will impact moment
Sliding filament theory
Ach is released through a neuron onto the muscle receptors. This impulse continues to cause Ca+ from the sarcoplasmic reticulum into the t-tubules. The Ca+ binds to troponin which moves the tropomyosin exposing the actin binding sites. Myosin then binds with actin. Atp attaches to the myosin to move the actin toward the middle of the sarcomere causing muscle contraction.
6 ways to name a muscle.
Size, location, # of origin, location of origin, shape of the muscle, action of the muscle
Size of the muscle
Location of the muscle
# of origin
Location of origin
Shape of muscle
Action of the muscle
