Q

How was E cells different than C cells?

A

cells divided by matrix in C cells. Not in E cells. C cells are never external. C cells have lots of nerves and vessels

Q

What is Mesenchyme

A

Mesenchyme is a type of animal tissue comprised of loose cells embedded in a mesh of proteins and fluid, called the extracellular matrix. … Mesenchyme directly gives rise to most of the body’s connective tissues, from bones and cartilage to the lymphatic and circulatory systems

Q

Mast cell

A

Mast cell, tissue cell of the immune system of vertebrate animals. Mast cells mediate inflammatory responses such as hypersensitivity and allergic reactions. … Upon stimulation by an allergen, the mast cells release the contents of their granules (a process called degranulation) into the surrounding tissues.

Q

Fibroblast

A

A fibroblast is a type of biological cell that synthesizes the extracellular matrix and collagen, produces the structural framework (stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals.

21
Q

What does Regular Dense CT look like?

A

Shiny. Smooth. Neat lines of collagen fibers

22
Q

What is tendon

A

DRCT connecting muscle to bone

23
Q

What is a ligament

A

DRCT connecting bone to bone

24
Q

What is Aponeuroses

A

DRCT attaching muscle to muscle or muscle to bone

25
Q

What is the main function of DIrrCT?

A

Strength

26
Q

Where can you find DIrrCT?

A

valves of heart, bones, dermis

27
Q

What type of CT is freely branching electic fibers that have fibroblasts between them?

A

Elastic

28
Q

Expanding and contracting tissues such as lung, artierial walls, penis, etc require what type of CT?

A

Elastic

29
Q

What CT can handle the most stress?

A

Cartilage

30
Q

Chondrocyte

A

mature catilage cells

31
Q

What makes up cartilage?

A

Chondrocytes, collagen + elastic fibers all in jelly-like chondroitin sulfate

32
Q

How many types of cartilage?

A

3

33
Q

Gristle also know as

A

Hyaline cartilage

34
Q

What is Hyaline cart?

A

Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea. Hyaline cartilage is pearl-blue/grey in color, with a firm consistency and has a considerable amount of collagen. Full of proteoglycans. Plyable support

35
Q

What is hyaline’s function?

A

Hyaline cartilage provides mechanical support for the respiratory tree, nose, articular surfaces, and developing bones

36
Q

What is Fibrocatalige?

A

Fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. It owes its inflexibility and toughness to the former of these constituents, and its elasticity to the latter. It is the only type of cartilage that contains Type I collagen in addition to the normal type II.

37
Q

Where is firbocartilage found?

A

menisci of knee and pubic symphysis

38
Q

Elastic cart is what?

A

Elastic cartilage or yellow cartilage is a type of cartilage present in the outer ear, Eustachian tube and epiglottis. It contains elastic fiber networks and collagen type II fibers.[1] The principal protein is elastin.

39
Q

What are the 2 types of bone?

A

Compact + Spongey

40
Q

Primary unit of compact bone

A

Osteon

41
Q

Spongey bone does what?

A

Makes RBC’s. No osteons. Is a lattice-work of plates of bone filled with red marrow.

42
Q

Function of Compact bone?

A

Strong + dense

43
Q

What are the 3 types of cells in blood plamsa?

A

Erythrocytes, leukocytes + platelets

44
Q

Does a synovial membrane contain an epitheleal layer?

A

No. Only connective tiuues

45
Q

Function of Mucous membrane?

A

defence. lubricates and protects other tissues and traps foriegn substnaces

46
Q

Where is Synovial membrane found?

A

cavities of freely- moving joints (dairthroses)

47
Q

Which membrane allows organs to glide against eachother and body walls without issue?

A

Serous

48
Q

2 exmaples of Serous membanes?

A

Pleura (membrane that protects the lungs) + pericardium (membrane that protects the heart)
