Planes of the body
Transverse plane
Midsagittal / sagittal plane
coronal plane
Oblique
Front and back
Anterior and posterior
Up and down
Superior and inferior
Toward midline and away from midline
Medial and lateral
Close and away from trunk
Proximal and Distal
Layer of peritoneum that lines inside abdomen and pelvis
parietal peritoneum
which layer of peritoneum covers organs inside
Visceral peritoneum
Space between Visceral and parietal is called
Peritoneum space
6 Characteristics of Epithelial tissue
(Hi I Called Pablo And Adrian)
High regeneration capacity
Innervated
Cellularity
Polarity
Avascular
Attachment to basement membrane
Prevents molecules from traveling between epithelial cells
Tight junction
microfilaments around the tight junction and deep to the cell
Adhering junction
protein plaque
Desmosomes
channel that allows communication between cells
Gap junction
What is a Basement membrane
thin layer of extracellular matrix that lines most human tissue forming and supporting structure
Extracellular proteins and polysaccharides that are secreted locally
extracellular matrix
proteins and carbohydrates
Ground substance
diffusion
rapid exchange
located in air sacs of lungs
simple squamous
absorption and secretion
located in kidney tubules
simple cuboidal
absorption and secretion
located in the lining of intestines
nonciliated simple columnar
movement of material
located in uterine tube
ciliated simple columnar
protection
located in respiratory tract lining
pseudostratified columnar
protection
located in the dermis
Keratinized stratified squamous
protection
located in mouth and vagina
Nonkeratinized stratified squamous
protection and secretion
located in the sweat gland duct
stratified cuboidal
protection and secretion located in the male part urethra
stratified columnar
distend or recoil
lining of the bladder
Transitional
Epithelial cells become polarized along the apical-basal side
polarity
surrounds and protects
located in papillary layer & subcutaneous
has fibroblasts
Areolar connective tissue
covers some organs
stores energy, insulates
located in subcutaneous fat
has adipocytes
Adipose connective tissue
provides supportive framework
located in dermis
has fibroblast, WBC, reticular fibers
Reticular connective tissue
Resists stress in 1 direction
Located in tendons
has fibroblasts
Dense regular connective tissue
Resists stress in all directions
located in the dermis
has fibroblasts
Dense irregular connective tissue
allows stretching
located in the elastic arteries
has fibroblasts
Elastic connective tissue
Top layer of the epidermis
which proteins does it have inside
STRATUM CORNEUM
dead keratinocytes
After stratum corneum comes
what proteins are inside
STRATUM LUCIDUM
packed with eleidin
What comes below stratum lucidum
what proteins are inside
STRATUM GRANULOSUM
keratinocytes
What is below stratum granulosum
what proteins
STRATUM SPINOSUM
epidermal dendric cells
Lowest layer of epidermis
STRATUM BASALE
keratin, keratinocytes, and tactile cells
what 3 things color skin
Melanocytes, Hemoglobin, and Carotene
What are the 3 functions of the skin
Protection
Regulates Temp
Hold water
What are the 2 layers of the dermis
Papillary layers
Reticular layers
small projection of tissue at the base of a hair
papillary
deeper layer
reticular layer
Why do we need a reticular layer
it strengths the skin
Why do we need papillary layer
to regulate temperature
3 types of cartilage
Hyaline cartilage
Fibrocartilage
Elastic cartilage
Glassy matrix; chondrocytes in
lacunae
Smooths joint surfaces
Hyaline cartilage
Parallel collagen fibers in
matrix; chondrocytes in
lacunae
Absorbs shock
located in interverbal disk
Fibrocartilage
Contains many elastic
fibers and less collagen
fibers.
Found in the outer ear
and epiglottis.
Elastic cartilage
Growing taller
Interstitial growth
Growing wider
Appositional growth
What does osteoclasts do
dissolve bone matrix
What does osteoblast do
BUILDDD
form bone matrix
Compact bone
solid and relatively dense
external surface of long and flat bone
Spongy bone
internal surface of bone
open lattice of narrow plates called trabeculae
3 Sections of long bone
Diaphysis
Epiphysis
Metaphysis
Covers internal surface of bone
Active in bone remodeling, growth, and fracture repair
Endosteum
Covers external surfaces of bones
Dense irregular connective tissue
Active in remodeling, growth, fracture repair
Periosteum
2 kinds of transport
Passive transport
Active Transport
Does not require cellular energy
materials move down concentration gradient
Diffusion & Facilitated diffusion
Passive
Requires energy
Materials are moved against their concentration
gradients or in large quantities
Pumping and bulk transport
Active
Exocytosis
Endocytosis
Going outside
Going inside
What does water osmosis apply to
Water moves to the highest solute
What can’t cross what can cross
Size of molecule and charge of molecule
