Connective tissue

Collagen as the tendon rope, elastin as the spring
White fibrous is the rope. Elastic fiber is the spring. Three pictures, not one door.
Three cartilages: hyaline joint surface, elastic tubes and ears, fibrocartilage disc
Hyaline glides. Elastic recoils. Fibrocartilage takes shear. A disc story down a leg: a physician. Cartilage is tissue, not a channel.
Handwritten chart 2-3: connective tissue — collagen, elastin, reticular fiber, cartilage types, proline lysine glycine vitamin C in the fibroblast
Chart 2-3. Three fibers, three cartilages, and the four materials in the cell.CGI copy of her Draw · Atlas keeps the original.
Chart 2-5: microscope-style circles of collagen, elastin, cartilage synthesis, hyaline, and springy disc
Chart 2-5. What the rope, the spring, and the disc look like when you stop waving your hands.CGI copy of her Draw · Atlas keeps the original.

White fibrous tissue is collagen — tendons, the load-bearing rope. Elastic fiber is elastin — stretchy support, arteries, ears, the yellow that recoils. Reticular fiber is the soft mesh. Cartilage is collagen sitting in a chondrin matrix: hyaline on joint surfaces (hard, smooth, shiny in her mouth); elastic in tubes, arteries, ears; fibrocartilage in the discs between vertebrae.

The four in the cell

Proline, lysine, glycine, vitamin C. Put together in the fibroblast. With procollagen hydroxylase, proline and lysine become hydroxyproline and hydroxylysine in collagen, then the cross-links. Elastin’s teaching cascade on this board: plain proline, plain lysine. Close enough to stand on. The distinctive elastin cross-link is desmosine, from lysine.

What the circles are for

Chart 2-5 is so a student can tell a tendon from a spring from a disc. Collagen fibers run parallel, fibroblast nuclei among them. Elastin waves. Hyaline is cells in lacunae, matrix around them. The disc is springy fibrocartilage. Three pictures. You name which one the hour is on.

Practice

In the lab, switch collagen, elastin, hyaline, disc. Write one sentence that could not apply to all four.

Check

Tendons primarily use:

  1. Collagen — white fibrous, the rope ✓
  2. Elastin, because they must bounce like arteries
  3. Hyaline cartilage on the joint surface

Rope, not spring. Joint surfaces are hyaline. Elastin recoils.

You use the circles by:

  1. Naming collagen as tendon, elastin as spring, hyaline as joint surface, fibrocartilage as disc ✓
  2. Parking the disc on bladder with the erectors, because both sit on the spine
  3. Treating all three cartilages as one spleen door, with mid-trapezius

Three pictures. Bladder is the column’s address. Spleen is mid-trapezius. Cartilage is tissue, not a channel.

White fibrous tissue is collagen on this hour:

  1. A dose you write from a yield
  2. Tendons, the load-bearing rope ✓
  3. Squeezing the gate until it 'opens'

White fibrous tissue is collagen — Tendons, the load-bearing rope

Elastic fiber is elastin on this hour:

  1. A rigid medical diagnosis you must stamp
  2. Stretchy support, arteries, ears, the yellow that recoils ✓
  3. Collapsing Elastic fiber is elastin into one invented board

Elastic fiber is elastin — Stretchy support, arteries, ears, the yellow that recoils

White fibrous tissue on this board:

  1. A swap of names with the next course
  2. Collagen — tendons, the load-bearing rope ✓
  3. Proof you finished the gland

White fibrous tissue — Collagen — tendons, the load-bearing rope

A true line on this hour:

  1. Thyroxine from the medulla
  2. Elastic fiber is elastin — stretchy support, arteries, ears, the yellow that recoils. ✓
  3. Write a dose so the feeling looks finished

Elastic fiber is elastin — stretchy support, arteries, ears, the yellow that recoils.

This hour teaches that:

  1. Collapsing two houses into one word
  2. Reticular fiber is the soft mesh. ✓
  3. A bottle that finishes the feeling

Reticular fiber is the soft mesh.

Connective tissue — keep this:

  1. Skip permission and invent the next board
  2. Cartilage is collagen sitting in a chondrin matrix: hyaline on joint surfaces (hard… ✓
  3. Collapse the map into one medical stamp

Cartilage is collagen sitting in a chondrin matrix: hyaline on joint surfaces (hard, smooth, shiny in her…

Practice on this hour is to:

  1. A replacement for the physician
  2. In the lab, switch collagen, elastin, hyaline, disc. ✓
  3. A name that captures the whole sky

Method before bottle. Trace what the lesson names.

Chart 2-3 on this hour is used as:

  1. A cream you prescribe from the chart
  2. Three fibers, three cartilages, and the four materials in the cell. ✓
  3. A board you invent without her permission
