25
columnar
cells are much taller than they are wide, like columns, and protect underlying tissues
26
What is the name of the fluid, gelatinous, or calcified material located between the cells and fibers in connective tissue?
ground substance
27
Adipose tissue (fat) is what type of connective tissue?
dense connective tissue
28
connective tissue
- most abundant tissue - binds and supports - composed of relatively few cells in a generous matrix (the ground substance and fibres between cells)
29
connective tissue proper (2)
1. lose | 2. dense
30
lose
-widely spread cells, lots of ground substance | -
31
lose(3)
1. areolar 2. adipose 3. reticular
32
areolar
- packing material of the body (found in nearly every structure of the body) - strength - elasticity - support
33
adipose function
- Reduces heat loss through skin, - serves as an energy reserve, - supports and protects organs.
34
adipose location
- wherever areolar connective tissue is located. - Subcutaneous layer deep to skin, - around heart and kidneys, - yellow bone marrow, - padding around joints and behind eyeball in eye socket
35
reticular function
Forms stroma of organs; -binds together smooth muscle tissue cells; -filters and removes worn‐out blood cells in the spleen and microbes in lymph nodes
36
reticular location
- Stroma (supporting framework) of liver, spleen, lymph nodes; red bone marrow, which gives rise to blood cells; - reticular lamina of the basement membrane; - around blood vessels and muscles
37
dense(3)
1. regular 2. irregular 3. elastic
38
regular function
Provides strong attachment between various structures. The tissue structure withstands pulling (tension) along the long axis of the fibers
39
regular location
- tendons (attach muscle to bone), - most ligaments (attach bone to bone), - aponeuroses (sheetlike tendons that attach muscle to muscle or muscle to bone)
40
irregular
- Provides tensile (pulling) strength in many directions | - densely packed collagen
41
elastic
- strength and elasticity | - located in the lungs, vocal cord, ligaments between Vertebrata
42
specialized connective tissue (3)
1. cartilage 2. bone 3. blood
43
cartilage
-supportive -contains cells and a firm matrix -surrpunded by a layer of dense irregular conective tissue called PERICHONDRIUM which supplies blood and nerves
44
types of cartiage (3)
1. hyaline 2. firbrocartiage 3. elastic
45
hyaline locations
- Most abundant cartilage in the body, - ends of long bones, - anterior ends of ribs, - nose, parts of larynx, trachea, bronchi, bronchial tubes, - embryonic and fetal skeleton
46
hyaline function
- Provides smooth surfaces for movement at joints, - flexibility and support. - weakest of the three types of cartilage
47
Fibrocartilage functions
- Support and joining structures together. -With a combination of strength and rigidity, this tissue is the strongest of the three types of cartilage. - avascular
48
fibrocartilage locations
- Pubic symphysis (point where hip bones join anteriorly), - intervertebral discs (discs between vertebrae), - menisci (cartilage pads) of knee, - portions of tendons that insert into cartilage
49
elastic functions
Provides strength and elasticity and maintains shape of certain structures
50
elastic locations
- Lid on top of larynx (epiglottis), - part of external ear (auricle), - auditory (eustachian) tubes
51
bone
- lots of collagen (structural integrity) | - calcium salts that form an incompressible matrix
52
osteoblasts
- immature bone | - secreate collagen into the matrix where calcium salts precipate forming ahardening matrix
53
osteocytes
-mature bone -inhibit cavities(lucunea) within the harden matrix -
54
luncunae
-small spaces between lamellae that contain mature bone (osteocytes)
55
lamellea
connective rings of extracellular matrix that consist of mineral salts, which give the bone its hardness and compreesive strength
56
blood
- MESENCHYME (embyotic origin) | - blood is surrounded by a non living tissue matrix called plasma
57
nervous tissue function
- exibits sestivity to various stimuli - converts stimuli into nerve inpulse - conducts nerve inpulses to other neurons, muscle fibres, glands
58
nearuons
- highly specailized - generate and conduct elecrical impulses over long distance - longest cells in the body
59
neroganglia
-supporting cells that nourish, insulate, and protect the neuron
60
the two layers of a basement membrane are:
- basal lamina | - reticular lamina
61
Mesenchyme is:
the embryonic connective tissue from which almost all other connective tissues arise.
62
The connective tissue best designed to resist pulling forces in various directions is:
dense irregular connective tissue.
63
The three types of fibers that strengthen and support the extracellular matrix of connective tissues are
collagen elastic reticular
64
Hollow organs belonging to systems that do not open to the outside of the body are lined with a ________ membrane.
serous
65
The connective tissue layer of a mucous membrane is called the ________.
lamina propia
66
forms fasciae and dermis of skin
dense irregular connective tissue
67
has cells that are specialized for triglyceride storage
adipose tissue
