Q

What is the function of cartilage tissue?
What are other traits?

A

The function of cartilage tissue is to support, protect and cushion

-Avascular and limited regenerative, surrounded by perichondrium (CT), that assists with growth of the cartilage and resist outward expansion when there’s pressure

Q

What is the growth of cartilage?

A

Appositional growth and interstitial growth

22
Q

What is appositional growth?

A

Chondroblasts in the perichondrium start producing matrix at the periphery of the cartilage and then differentiate into chondrocytes

23
Q

What is interstitial growth?

A

Chondrocytes divide within their lacunae. New chondrocytes transform into chondroblasts and secrete more matrix, which increases the mass of the cartilage
= denser cartilage

24
Q

What is the function of bone?

A

support
movement
protection
mineral storage
hematopoiesis
energy storage
energy metabolism –> produce hormone osteocalcin

25
Q

What are the two bone types?

A

Compact bone and Spongy Bone

26
Q

What is the structure of compact bone?

A

Dense outer layer of bone
80% of the mass of our skeleton
site for calcium storage

27
Q

What is the structure of spongy bone?

A

cancellous or trabecular bone
found at the ends of long bones
porous and vascular
red bone marrow
yellow bone marrow

28
Q

Muscle Tissue

A

Osteon = haversian system which has the artery with capillaries, vein, nerve fiber –> lamellae –> collagen fibers

29
Q

Osteon

A

nerve, vein artery –> centralaversion canal –> canaliculi—> lamellae –> osteocyte in lacuna

30
Q

muscle cells/fibers

A

myoblasts, multinucleated, sarcolemma, sarcoplasm
myofibrils
- sarcoplasm –> sarcoplasmic reticulum

sarcoplasmic reticulum and transverse tubules

31
Q

sarcomere

A

makes up myofibrils and contains myfilament (actin and myosin)
ZHZ disc
IAI band

32
Q

sarcomere contraction & sliding filament theory

A

zone of overlap short sarcomere is long
zone of overlap is long and sarcomere is short

33
Q

Muscle actions

A

primary mover is agonist more
(biceps
secondary mover synergist less

antagonist muscle that can oppose (triceps

34
Q

types of contraction

A

isometric –> length remains the same
isotonic –> cocentric = action shorten and eccentric = cannot

35
Q

4 types of bone cells

A

osteogenic cells, osteoblasts, osteoid, osteocytes, osteoblasts

36
Q

lamellae

A

outer, interstitial and concentric

37
Q

early development

A

embryonic period is 8 weeks
fetal which is 9th week to birth
prenatal is both

38
Q

1st week

A

0hr = fertilization of egg and sperm
2nd day = blastomeres
3rd day= enters uterine cavity
4th day= blastogenesis –> trophoblast, embryoblast
6th day = implantation

39
Q

cleavage

A

embryoblast, blastocyst cavity, tryphoblast

40
Q

6th day implantation

A

trophoblast erodes into uterine wall and hypoblast is developed at the 2nd week

41
Q

2nd week

A

hypoblast
primordium of amniotic cavity
embryoblast differentiate into amnioblasts and epiblasts, hypoblast lines trophoblast –> bilaminar embryonic disc
disc is the developing embryo which is made of hypoblast and epiblast

chorionic cavity

42
Q

gastrulation

A

3 germ layer : hypoblast –> endoderm, epiblast and hypoblast –> mesoderm, remaining epiblast –> ectoderm

43
Q

notochord

A

primary inductor, form cellular tube

44
Q

germ layer

A

ectoderm, mesoderm, endoderm

45
Q

notochord

A

defines the axis of the embryo

46
Q

mesoderm patterning

A

fills the space everywhere but the mouth, anal and notochord

47
Q

body folding

A

fold in median and horizontal planes,
cranial fold=foregut, caudal fold=hindgut, lateral fold=midgut

48
Q

three region of mesoderm

A

paraxial –> longitudinal
intermediate –> thins out laterally
lateral –> makes surround heart, lung and abdominal and pelvic organs

49
Q

neurulation

A

primary induction:
neural tube = brain and spinal cord, neural crest cranial, spinal and autonomic ganglia

50
Q

integumentary system

A
