dense regular
|
tendons (she drew a diagram of bones, tendons attaching them)
|
|
|
dense irregular
|
aoineurosis = flat tendons, on joint capsules
|
|
|
ureter
|
transitional
|
|
|
where do you find connective tissue
|
just below the basement membrane (1st 20%)
|
|
|
ligament
|
bone to bone
|
|
|
where do you find embroyonic connective tissues?
|
embryos, embryonic ___ anything to do w/embryos
|
|
|
reticular conn tissues is associ with ______-
|
Lymphatic organs (ex: lymph nodes, bone marrow & spleen)
|
|
|
5 types of connective tissues
|
blood, bone, cartilage
|
|
|
KNOW cartilage has ___-
|
same comopnents, but cells are found in lacunae, chondrocytes, chondroblasts
|
|
|
KNOW 2 types of bones
|
cancerous bones & compact/spongy bones
|
|
|
ON lab exam: it's compact bone that has tree trunk structure, called osteon
|
spongy bone
|
|
|
KNOW: Haversian system ( = osteon), central/Haversian canal (has blood vessels, nerve & lymph), osteocytes (black spidery structure), lacuna (contains osteocytes),
|
(your bone sores minerals)
|
|
|
nervous tissues main function
|
- excitable, stimulatable to conduct signals along neurons for communication to nerve, muscle, or gland
|
|
|
muscles tissues's main function
|
excitable & contractile, for movement
|
|
|
(picture of nervous tissues) : neuron
|
note the cells are very dark: the dark area = rought ER, lot of protein, which become neurotransmitters (these cells are long) cell body in spinal cord
|
|
|
picture of skeletal muscle)
|
only voluntary movement - not involuntary, located mostly in skeletal muscles attached to bones or occasionally to skin
|
|
|
Embryology (also see Tortera p. 160) Start: oocyte (ovum) imagine an egg picture, spermatocyte must fertilze egg cell or oocyte(these are germ cells with 1/2 no chromosomes, they divide by meiosis)
|
.. 23 + 23 = 46. the process continues mitotically unitl you get a morula, blastula (w/a ring structure) -where outside = support tissue and middle = embryo. Imp: next stage of germ development where cells differentiate into 3 layers: ectoderm, mesoderm, and endoderm
|
|
|
how many types do embryo cells differentiate into & what's this process called?
|
gastrulation
morula -> blastula -> gastrula ( see book p. 1111 - 1126 ) |
|
|
3 embryonic germ layers of gastrula ( = embryo)
|
1 ecotoderm (forms nervous tissue, a lot of epithelium)
2 mesoderm (forms mostly muscle & connective tissue) 3 endoderm (forms some epithelium) |
|
|
mesoderm give rise to ______
|
- primarily muscle & connective tissues
|
|
|
endoderm give rise to ______
|
linings, epithelial linings tracts, (GI tracts, respiratory, urinatory, reproductive)
|
|
|
ectoderm give rise to ______
|
forms nervous tissue, a lot of epithelium
|
