Q

Spongy Bone

A

Structure: Contains small plates and bars of bone called trabeculae with cavities for bone marrow
Function: Helps to lessen the weight of a bone while still providing strength
Location: At the end of a long bone

16
Q

Compact Bone

A

Structure: Has a central canal called the osteonic canal with a ring formation around it called lamellae
Function: Provides protection and strength
Location: Outer layer of bone, particularly around the shaft

17
Q

Skeletal Muscle

A

Structure: long, thin cells, have multiple nuclei, striations
Function: Pulls on the bone to make us move
Location: Attached to bones

18
Q

Cardiac Muscle

A

Structure: Shorter cells, have noticeable divisions/connections between cells which are called intercalated discs, striated
Function: Generated ATP to continuously make the heart pump
Location: Heart

19
Q

Smooth Muscle

A

Structure: Long-thin filaments that are not striated
Function: Help with digestion and nutrient collection
Location: Found in hollow organs ex: blood vessels

20
Q

Nerve Tissue

A

Structure: Looks like a star and contains dendrites, cell body, and axon
Function: Convey information by electrical signaling
Location: Brain and spinal cord

21
Q

Epithelial Tissue

A

Structure: Squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers
Functions: Covers the body and lines cavities and glands within the body
Protect the body from physical damage, control what substances enter and leave the body
Provide sensory information
Secrete various substances

22
Q

Connective Tissue

A

Function: Giving the body and organs the strength to resist external forces
Protect internal organs
Allows for movement of muscles

23
Q

Types of fibers in Connective tissues

A

Collagen fibers- thick strong and resistant to stretch that
Reticular Fibers-thinner and less strong and keep cells in place
Elastic fibers- thinnest can be stretched and can spring back to the place

24
Q

Types of tissues

A

ET= Epithelial Tissue
LCT= Loose Connective Tissue
DCT = Dense connective tissue

25
Q

Loose Connective Tissue

A

Has cells and an extracellular matrix with fibers running through it

26
Q

Dense Connective Tissue

A

Has few cells and its extracellular matrix is mostly made of fibers

27
Q

Cartilage

A

Structure: Contains Chondroblasts that secrete the extracellular matrix which contains collagen fibers and proteoglycan molecules. These molecules bind to water molecules which allows cartilage to be resistant to compression

Function: Support flexibility and minimize friction

Location: Found at the end of bones and between bones

28
Q

Bone

A

Structure: Made of osteocytes which secrete the extracellular matrix of bone that contains collagen fibers and calcium salts

Function: Support and protect the other tissues
Calcium and phosphate storage
House bone marrow

29
Q

Muscle Tissue

A

Structure: Skeletal and cardiac tissue are striated and smooth is uniform
Function: To allow our body to move
Location: Bones, heart, and organs
