transitional epithelum
34
endocrine glands
LACK DUCTS and secrete their products into the blood stream
35
exocrine glands
CAN HAVE DUCTS and go any where that isnt the blood
36
merocrine gland (eccrine gland)
packages and releases through exocytosis
37
examples of merocrine glands
swear, lacrimal, salivary, pancreas and gastric
38
apocrine glands
content is produced and pinched off
39
apocrine gland examples
mammary gralnds, ceruminous glands of the ear, and smelly sweat
40
holocine glands
accumulation of a product then boom
41
holocrine glands example
sebacous glands of the skin
42
what do all connective tissues have in common?
cells, protein fibers and ground substance
43
cells of the connective tissues
fibroblasts, adipocytes, mesenchymal, fixed macrophages, wandering cells
44
types of protein fibers
collagen, reticular and elastic
45
describe collagen fibers
unbranched, cable like, strong flexible and resistant to streching
46
desscribe reituclar fibers
thinner than collagen but is branching foudn in the stroma, connective tissue framwork of organs such as lymphnodes spleen and liver
47
describe elastic fibers
strechy recoil,g go back to orginal shape
48
ground substance
glue, have GAGS
49
what are GAGS
glycoaminoglycans, poolysaccharide that attract and absorb water and affect the thickness of ground substance
50
proteoglycan
when GAG is linked to a protein which acts as a flue to bond connective tissue and ffibers to ground substance
51
general functions of connective tissue
physical protection, support, transport, binding of srtuctures, immune protection, storage
52
types of embryonic connective tissue
mesnchyme - fetus muscous conenctive tissue- umbillical cord
53
connective tissue proper divided into what groups
loose and dense
54
loose connective tissue
fewer cells and protein fibers than dense abundant ground substance
55
loose connective tissue examples
areolar adipose reticular
56
areolar tissue function
protects tissues and organs, bunds skin and stuff to deeper tissue
57
areolar tissue location
papilary region of the dermis surrounds organs, nerve cells, muscle cells and parts of blood vessel walls
58
adipose connective tissue location
subcutaneous layer, surrounds and covers some organs
59
adipose connective tissue function
stores energy, insulates, cushions and protects
60
reticular connective tissue location
spleen, lymphnodes and red bone marrow
61
reticular connective tissue function
provides (stroma) supportive framework tp lymphatic organs
62
dense connective tissue
composed primarily of protein fibers and less ground substance than loose, collagen fibers are typically dominant
63
examples of dense connective tissue
dense regular connective tissue, dense irregular and elastic
64
dense regular connective function
attatches bone to bone and muscle to bone collagensss
65
dense regular connective location
tendons and ligaments
66
dense irregular connective function
withstand stress in all directions, has collagens
67
dense irregular connective locaation
reticular layer of the dermis, epumysium covering skeletal msucle, coveringcartilages
68
elastic conenctive tissue loaction
walls of elastic arteries, trachea, vocal cords
69
elastic connective function

71
two types of supporting connective tissue
cartilage and bone
72
types of cartilage tissue
hyaline, fibrocartilage and elastic cartialge
73
chondrocytes
mature cartilage cells which occupy small spaces called LACUNAE is avascular
74
hyaline cartilage fucntion
support, forms most of fetal skeleton
75
hyaline cartilage location
tip of nose, costal cartilage , growth plates and articular ends of long bones
76
fibrocartilage location
intervertebral discs, pubic symphsis, mensinci of knee joints
77
fibrocartilage function
weight bearing cartilage that resists compression, acts sometimes as a shock absorber
78
elastic cartilage function
maintain shape while permitting LOTS of flexibillity
79
elastic cartilage location
external ear, epiglottis
80
bone connective tissue
makes up most of bones, extensively vascularized,
81
osteocytes
mature bone cells and are housed in lacunae
82
fibroblasts
reticular cells
83
types of fluid connective tissue
blood and lymph
84
blood tissue
made of formed elements , ground substance is plasma,
85
blood function
transport gases, leukocytes, platlets lots of stuff
86
blood location
primary in blood vessels and in heart
87
muscle tissue
highly vascularized, responsible for most types of movement
88
types of muscle tissue
skeletal, cardiac and smooth
89
skeletal msucle tissue function
moving skeleton and thermoregulation
90
skeleteal msucle location
attatches to bone and sometimes skin, forms external urethral and anal sphicters
91
cardiac muscle tissue function
pump blood through heart
92
cardiac muscle tissue location
heart wall
93
intercalated discs
in ONLY cardiac muscle tissue, intercellular junctions between cells made of desmosomes and gap junctions
94
