Cells
These molecules form the basic structure of the cell membrane
phospholipids
This tissue type includes bone, blood, fat, and tendons.
connective tissue
This muscle on the forehead raises the eyebrow
frontalis
These joints connect bones using dense regular connective tissue and have no joint cavity.
fibrous joints
These cells are the main functional units of the nervous system and transmit electrical impulses
What are neurons
Because of the phospholipid structure, the cell membrane spontaneously arranges into this double-layered structure.
phospholipid bilayer
This tissue covers all body surfaces, lines organs, and forms glands.
epithelial tissue
This circular muscle surrounds the eye and allows you to blink or squint
orbicularis oculi
These immovable joints are found only in the skull and eventually fuse into synostoses.
sutures
This part of a neuron receives incoming signals
dendrites
This type of fatty acid contains double bonds that create kinks in phospholipid tails.
Unsaturated fatty acids
This tissue is responsible for movement and includes skeletal, cardiac, and smooth types.
muscle tissue
This smiling muscle pulls the corners of your mouth upward
zygomaticus major
This type of cartilaginous joint literally means “junction of cartilage” and is immovable
synchondrosis
This division of the nervous system includes the brain and spinal cord
central nervous system
These membrane-spanning proteins help specific molecules cross the membrane during facilitated diffusion.
Channel proteins
This tissue contains neurons and glial cells and is specialized for communication
nervous tissue
This long neck muscle helps you turn and tilt your head
sternocleidomastoid
Epiphyseal plates and the joint between the first rib and sternum are examples of this type of joint
synchondroses
Nerves that connect the CNS to the rest of the body belong to this division
peripheral nervous system
The movement of water across a semipermeable membrane toward a higher solute concentration is called this.
Osmosis
Epithelial tissue with a single layer of cells is described with this term
simple epithelium
This large triangular muscle on the shoulder helps you abduct your arm
deltoid
These joints are slightly movable and are united by fibrocartilage, acting as strong shock absorbers
symphyses
This tiny gap between neurons is where neurotransmitters are released
synapse
