25
what does and doesn't increase when fat store increases?
size of cells not number
26
4 locations of adipose tissue
abdomen, heart, bone marrow, eye socket
27
4 functions of adipose tissue
protection, cushion, energy storage, insulation
28
example of adipose acting as protection
adipose tissue in the abdomen to protect the heart and lungs
29
example of adipose acting as a cushion
found in eye-sockets to cushion eyes
30
how does adipose insulate the body
by preserving heat
31
property of reticular tissue
thin network of reticular fibers in 3D
32
function of reticular tissue
provides framework for some internal organs (ex: spleen)
33
3 types of dense connective tissue
regular, irregular, and elastic
34
components of regular dense connective tissue
densely packed collagen fibers with some elastic fibers, and some fibroblasts
35
pro of regular dense connective tissue
strong
36
con of regular dense connective tissue
has less blood supply
37
2 examples of structures made of regular dense connective tissue
tendons and ligaments
38
components of irregular dense connective tissue
very unorganized fibers, collagen fibers, and fibroblasts
39
1 example of a structure composed of irregular dense connective tissue
dermis
40
3 components of elastic dense connective tissue
elastic fibers with some collagen and fibroblasts
41
2 examples of structures composed of elastic dense connective tissue
large vessels (like aorta), and airways
42
large vessels and airways contain elastic dense connective tissue since
they need to be able to expand, change shape, and dilate blood vessels that then can bounce back to position
43
5 types of specialized connective tissue
cartilage, blood, bone, muscle, and nervous
44
property of cartilage tissue
rigid collagenous fibers
45
what structure surrounds cartilage tissue
the perichondrium
46
what does the perichondrium supply to the cartilage tissue
an inefficient amount of blood
47
how does blood from the perichondrium get into cartilage tissue
through diffusion
48
the cells within cartilage tissue divide ___ and the tissue heals ___
slowly, poorly
49
4 functions of cartilage tissue
protection, support, attachment, and bone modeling
50
what type of cell forms cartilage tissue
chondrocytes
51
where are chondrocytes embedded into
the matrix
52
what are the two types of cartilage
elastic and hyaline
53
where is hyaline cartilage located?
at the ends of ribs
54
where is elastic cartilage located?
makes up the external portion of the ears
55
which type of cartilage tissue is more flexible?
elastic cartilage
56
why is elastic cartilage more flexible than hyaline cartilage
because it contains more elastic fibers
57
name of the space where chondrocytes are housed
lacuna
58
6 properties of bone tissue
most rigid tissue, formed by osteoblasts, composed of calcium and phosphorus, provides support and protection, salt storage, and bone marrow forms blood cells
59
when osteoblasts surround themselves in matrix, they become
osteocytes
60
what makes up blood's ECM
plasma
61
what type of cells are found in blood
RBC, WBC, and fragments of platelets
62
3 substances that blood transports
to transport hormones, nutrients, and waste products
63
2 properties of muscle tissue
contractile, contains muscle fibers
64
contractile property means that muscles
can contract and only move in one direction
65
when a muscle contracts the muscle fibers
shorten and thicken
66
3 types of muscle tissue
skeletal, smooth, and cardiac
67
4 properties of skeletal muscle tissue
attach to bones, have striations, are under voluntary control, and each cell contains more than one nucleus
68
striations
perpendicular lines that run through muscle fibers and designate sarcomeres
69
4 smooth muscle tissue properties
no striations, surrounds hollow internal organs, involuntary movement, and each cell contains only one nucleus
70
4 cardiac muscle properties
only found in the heart, have some striations, cells are branches and connected, moves involuntary
71
what 2 types of intercellular junctions are found in cardiac tissue?
gap junctions and desmosomes
72
3 nervous tissue locations
brain, spinal cord, peripheral nerves
73
basic cell of nervous tissue
neuron
74
type of intercellular junction found in nervous tissue
gap junctions
75
nervous tissue function
sends signals to rapidly deliver info and determines responses
