Tissue and Terminology Flashcards
Types of tissue in the body
Epithelial, connective, muscle, nervous
Types of epithelial tissue
Epithelia and glands
Types of epithelial glands
endocrine and exocrine
Exocrine
secretes substances through a duct, onto a surface.
Endocrine
secretes substances through a duct, into the blood system
Functions of epithelial tissue
- Provides protection
- controls permeability
- Provide sensation
- Provide specialized secretions
Types of connective tissue
Proper, fluid, supporting
types of proper connective tissue
loose and dense, collagen and elastic fibres
types of fluid connective tissue
blood and lymph
types of supporting connective tissue
cartilage and bone
functions of connective tissue
- structural framework
- transport fluids and dissolve materials
- protect delicate organs
- Support, surround and interconnect other types of tissue
- Store energy, triglycerides
- defend from invading microorganisms
collagen fibres
resists tension and pulls back
elastic fibres
doesn’t resist tension, stretches and then recoils
types of muscle tissue
skeletal, cardiac, smooth
nervous tissue
receives and gives signals to effectors
examples of effectors
usually a muscle or gland that responds to signals from nervous tissues.
neurons
sends electrical messages
neuroglia (glia)
hold neurons together and support cells. Repair damage after injury and provide nutrients.
homeostasis
Uses regulatory mechanisms to ensure systems stay within set points
feedback
controlled variables move too far from the set point and responses from the body attempt to move the variable back to normal
feedforward
an action due to the anticipation of an event that alters the change of variable
superior
higher than
inferior
lower than
medial
closer to the centre of the body
lateral
further from the centre of the body
proximal
higher than, on a limb
distal
lower than, on a limb
anterior (ventral)
further infront of
posterior (dorsal)
further behind
deep
further from surface
superficial
closer to surface
sagittal plane
divides the body into left and right parts
coronal plane
divides the body into front and back parts
transverse plane
divides the body into top and bottom parts
sagittal plane movements
backwards and forwards movements
coronal plane movements
side to side movements
transverse plane movements
rotational movements
