What are the four main types of tissues
Epithelial
Connective
Muscle
Nervous
What is the epithelium lining the inside the structure called
Endothelium
How to classify the epithelial tissue
Number of layers of cells: simple/stratified
Shape of the cells : squamous, cubiodal, columnar
What is a group of epithelial cells that produce and secrete protein molecules such as hormones called
Glandular epithelia
what the two different types of glands and what are their functions
Endocrine glands: produced
hormones directly released into
bloodstream or lymphatic system.
Eg. pituitary and adrenal gland
* Exocrine glands releasing
secretions via duct directly into
nearby areas. Eg. pancreas, and
salivary gland
what are the three different types of connective tissues
-loose (adipose)
-dense (ligament)
-specialised (cartilage, bone,blood)
what are the three major components that all connective tissues must contain
-extracellular fibre (collagen,reticular,elastic)
-ground substance
-cells (fixed cells + wandering cells (wbc & rbc)
what is the difference between loose and dense conncetive tissues
loose: loose network of collagen fibres -> provide support and flexibility (eg under skin)
dense: densely packed collagen fibre bundles -> provides strength (liganment and tendons)
what is a unit of bone tissue (one tree trunch) called
osteon and it has a central canal
what are the three different types of cartilage and what are they made up of
Hyaline cartilage: randomly arranged collagen fibres. It is the
most common cartilage in the body (eg. framework for the nose,
trachea
* Elastic cartilage: Contain numerous elastic fibres. It occurs
where support with flexibility is required, e.g. the external ear
* Fibrocartilage: consists of mainly collagen fibres but fewer
chondrocytes than hyaline cartilage, e.g. in the inter-vertebral
discs
what are the three different types of muscle tissues
Skeletal muscle: predominant muscle type
which moves the skeleton
➢ Cardiac muscle: heart muscle.
➢ Smooth muscle: found in digestive tract,
blood vessel etc.
what are the two types of cells that make up the nervous tissue
neuron and neuroglia (such as schwan cells that make up the myelin sheath )
what are the different body cavities
under the dorsal cavity: cranial cavity, spinal cavity
ventral cavity: thoracic cavity (pericardal cavity: heart)
-abdominal/ peritoneal cavity
-pelvic/ cavity
what is the structure separates the thoracic cavity from
abdominal cavity
diaphragm
what is the name of the serous membrane lines insides of the cavity
pariental membrane
