Body Orientation
examines how the body functions
what is the study of physiology?
lipids with attached carbohydrate groups
what is a glycolipid?
Four basic/primary tissue types
what are epithelial, connective, nervous, and muscle?
Empty-looking cells with thin margins; nucleus pressed against cell membrane.
energy storage, insulation, cushioning
what is adipose tissue?
five main functions of the skin
away from the midline, on the other side of of
what is lateral?
unique fuzzy coat external to the plasma membrane; function is to protect cell
what is the glycocalyx?
singe row of thin cells; secretes serous fluid
what is simple squamous epithelium?
densely packed, randomly arranged, collagen fibers
deeper layer of skin; capsules around organs
what is dense irregular connective tissue?
the tissue that makes up the epidermis
closer to the point of attachment of a limb to the body trunk
what is proximal?
Embedded within, and extend across the phospholipid bilayer.
What is an integral protein?
Multiple cell layers with cells becoming flat and scaly toward surface; protection
What is known as keratinized stratified squamous?
Usually covered by perichondrium; eases joint movement, holds airway open
what is hyaline cartilage?
the 5 types of cells of the epidermis
what are stem cells, keratinocytes, melanocytes, tactile (merkel) cells, and dendritic cells
The main cavity that houses the brain and spinal cord
what is the dorsal cavity?
net movement of ions or molecules from an area of greater concentration to an area of lesser concentration; due to kinetic energy
what is the process of diffusion?
tear glands, sweat glands, pancreas, gastric glands
what are known as merocrine glands?
protects and assists neurons; "housekeepers" of nervous system
what is neuroglia or glial cells?
found on palms and sole, and corresponding surfaces on fingers and toes; has sweat glands, but no hair follicles
what is thick skin?
blood clotting
What is a positive feedback?
the solution has a lower concentration of solutes, a higher concentration of water than in the cytosol
what is a hypotonic solution?
Secretion of a mixture of cell fragments and synthesized substance; oil glands of scalp/eyelids
receive signals from other cells; transmit messages to neurosoma
what are dendrites?
layers of epidermal strata from deep to superficial
Stratum Basale
stratum spinosum
Stratum granulosum
Stratum lucidum
Stratum Corneum
