Cells
Osmosis
The diffusion of water through a selectively permeable membrane.
Higher Semipermeable Lower Containment --> Concentration --> Containment Concentration Concentration
Types of Tissues
Connective, Muscle, Epithelial, Nervous
Functions of the skeletal system
It gives your body its shape, allows movement, makes blood cells, provides protection for your organs and stores minerals
Types of Muscle
Smooth / Striated / Cardiac
Involuntary/Voluntary/involuntary
in walls of hollow visceral organs/skeletal/heart
General functions of the nervous system
send messages from various parts of your body to your brain, and from your brain back out to your body to tell your body what to do
Diffusion & Facilitated Diffusion
Molecules tend to spread out, moving from areas of high concentration to low concentration. ^ Requires no energy: Passive Transport Facilitated Diffusion uses proteins as passageways
Epidermolysis bullosa
connective tissue disorder
Parts of the bone
Epiphysis- ends of bone
Diaphysis- middle
articular cartilage-spongy bone-epiphyseal line-red bone marrow-endosteum-medullary cavity-yellow bone marrow-articular cartilage
Structure of Skeletal Muscle
Epimysium/perimysium/endomysium/
skeletal muscle/muscle fascicle/Muscle fibre/myofibril
Anatomy of a neuron
Dendrite-cell body(nucleus)-axon[Schwann cell(covered in myelin sheath)-node of ranvier]-axon terminal
Cell Organelles & Functions
Endoplasmic Reticulum: Transport System ^R-ER: Has ribosomes on surface which make protein.^S-ER: Lipid Synthesis
Golgi Apparatus: Package & Delivery of proteins produced by the ribosomes. ^Proteins are exported through vesicles.
Lysosomes:
cartilage tendon ligament
muscle to bone
bone to bone
gel-like padding between bones that protects joints and facilitates movement
Skull (all bones) and sutures
label them
Neuromuscular junction
where motor nerve synapses with muscle

Neuroglial Cells and their functions
oligodendrocyte: generating and maintaining the myelin sheath around the axon
astrocyte:regulation of blood flow, homeostasis of extracellular fluid, ions and transmitters, energy provision, and regulation of synapse function, and synaptic remodeling
microglial cells: throughout the brain and spinal cord of the central nervous system
What is Cell Membrane and Transport?
Special membrane transport proteins are responsible for transferring such solutes across cell membranes.
matrix
the material (or tissue) in between a eukaryotic organism's cells
Pectoral Girdle & Upper limbs
Pelvic Girdle & Lower limbs
the clavicle and the scapula
sacrum and the coccyx
Muscular Dystrophy
Myasthenia Gravis
progressive weakness and loss of muscle mass.
Functions of the lobes of the brains
Mitosis
a process of cell duplication, in which one cell divides into two genetically identical daughter cells
Interphase / Prophase / Metaphase / Anaphase / Telophase
squamous cells
make up the middle and outer layers of the skin
Types of joints
Ball-and-socket: shoulder and hips allow backward, forward, sideways, and rotating movements.
Hinge joints: ingers, knees, elbows, and toes, allow only bending and straightening movements.
pivot: neck joints, allow limited rotating movements
Saddle:thumb, shoulder, and ear move up and down and back and forth.
Sliding Filament Theory
the sliding of actin past myosin generates muscle tension
