dense regular
tendons (she drew a diagram of bones, tendons attaching them)
dense irregular
aoineurosis = flat tendons, on joint capsules
where do you find connective tissue
just below the basement membrane (1st 20%)
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?
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
