Verified Solution 2024.
epithelial tissue
lines tracts and airways, maintain shape with water
connective tissue
loose, dense, fluid, supporting, fills internal space
loose connective tissue
holds organs in place attaches epithelial to other tissues
dense connective tissue
ligaments, tendons, a lot of collagen, resists tension, elastic
fluid tissue
blood, lymph
supporting tissue
cartilage and bone
nervous tissue
conducting cells and support cells, communication, regulates body functions
muscular tissue
skeletal, cardiac and smooth
skeletal muscle
tissue on the skeleton
caridac muscle
heart muscle
smooth tissue
lines hollow organs i.e. blood
sagital
coronal
Transverse
long bone
longer than wide, lever for movement, compact bone in diaphysis
short bone
mainly cancellous, similar width and length, weight bearing
flat bones
thin flat bones, mainly compact with some cancellous, point of muscle
attachment/protection
irregular bone
variable shape and function
skull compartments
facial bones, cranial vault, mandible
rib cage compartments
jugular notch, mandibrium, body, xiphoid process, 2 sets of 12 ribs, coastal cartilage
vertebral column compartments
cervical 7, thoracic 12, lumbar 5, sacrum 5 fused, coccyx 3-5
, pectoral girdle
clavicle and scapula
pelvic girdle
illium, ischium, pubis
upper limbs
humerus, radius, ulna, carpals 8, metacarpals 5, phalanges
lower limbs
femur, tibia, fibula, tarsals 7, metatarsals 5, phalanges
limb structure
1 proximal 2 distal hands/feet upper limb pronate and supinate
limb attachments
to the girdles, upper limb to pectoral, lower limb to pelvic
extracellular component of bone
organic 33% collagen resist tension, inorganic 67% mineral salts resist bending
osteoblasts
build bone live in subperiosteum
osteocytes
old osteoblasts, live in lacunae, communicate when to turn over bone
osteoclasts
clear bone, live in endosteum
osteon
layers of lamallae
lamallae
rings around the central canal made of collagen organised in opposing angles
central canal
where blood and nerves go through bone
lacunae
'pools' in the lamallae where osteoclasts live
canaliculi
how osteoclasts communicate from one lacunae to the next
periosteum
outside layer of bone allowing penetration of blood into bone
subperiostreum
layer below the periosteum where osteoblasts live (move in with the blood)
endosteum
inside membrane of the bone where osteoclasts live
trabeculae
structures of lamallae in cancellous bone
marrow
fluid in cancellous bone, red marrow produces red blood cells
osteoblasts cancellous
live in the blood
osteocytes cancellous
live in the lacunae on surface of trabeculae
ossification
production of bone beginning in the diaphysis
