What are the three types of connective tissue?

cartilage

"chondro" means

bone

"osteo" means

usually forms around skeleton, covers long bones

ex. around the ribs, cartilages of the nose, trachea

Where can hyaline cartilage be found?

cartilage: hyaline

What type of connective tissue is this?

external ear or nose

(low ability of regenerating)

immature cells

"blast" means...

mature cells

"cyte" means...

plasma

blood= cells+

blood

What type of connective tissue is this?

nucleus

immature rbc's have a _______; mature rbc's does not

Bone

What type of connective tissue is this?

cancellous bone doesn't have blood vessles in the center, instead the blood is on the outside. Compact bone has blood vessels in the center.

What is the difference between compact bone and cancellous bone?

around skeleton

skeletal muscle tissue is found...

only in the heart

cardiac muscle tissue is found...

in hollow structures (lungs, digestive system, urinary system)

smooth muscle tissue is found...

Skeletal (striated)

(the meat we eat)

What type of muscle tissue is this?

Cardiac (striated, syncytium, intercalated discs)

What type of muscle tissue is this?

Smooth (no striations, spindle like- diamond shaped)

What type of muscle tissue is this?

actin and myosin

What are the 2 proteins found in muscle?

Gap junctions where sodium passes in between muscle cells.

What are intercalated discs?

Nervous

What type of tissue is this?

neurons and glial cells (neuroglia)

Nervous tissue is made up of 2 cells:

Ends of the bone

Epiphysis

The shaft of the none which surrounds the medullary cavity.

Diaphysis

Cushions at the ends of the bones and allows for smooth movement.

Articular cartilage

Areas made of cartilage allowing for the growth of the bone

Epiphyseal Plate

long, short, flat, irregular, sesamoid

What are the 5 types of bones?

Compact bone, cancellous bone, medullary cavity (present/absent)

The anatomy of a bone of a bone consists of...

Skull, veterbral column, ribs, and sternum

The axial skeleton bones are:

forelimb, hindlimb, pelvis

The appendicular skeleton bones are:

What is the vertebral formula for a horse?

C7, T13, L6, S5, Cd 18-20

What is the vertebral formula for a cow?

C7, T13, L7, S3, Cd 20-23

What is the vertebral formula for a dog?

Lines, covers, secretes, and protects.

Epithelial tissue...

Connects, supports, and protects

Connective tissue...

Have twitchy and excitable cells; they contract and relax to create movement.

Muscle tissue...

Has one excitable cell- neuron; neuroglia are the supporting cells.

Nervous tissue...

epithelial tissue

Layers and shape

Epithelial tissue is classified by...

stomach

Where is simple columnar located?

shoulder, elbow, carpus, digits (short pastern, long pastern, coffin bone)

What four joints are in the forelimb?

hip, stifle/knee, tarsus, digits (short pastern, long pastern, coffin bone)

What four joints are in the hindlimb?

coming together

The prefix "syn" means...

Secretion, absorption
