Mesenchyme

A type of embryonic connective tissue that gives rise to various structures in the body, including muscle, bone, and blood. Mesenchyme is characterized by a loose arrangement of cells and a gel-like extracellular matrix.

Epithelial Tissue

A type of tissue that covers body surfaces and forms glands. Epithelial tissue is composed of closely packed cells with minimal extracellular matrix, serving functions such as protection, absorption, and secretion.

Muscle Tissue

A type of tissue responsible for movement in the body, consisting of cells that can contract and relax. Muscle tissue is classified into three types: skeletal, cardiac, and smooth.

Nervous Tissue

A type of tissue that transmits electrical impulses throughout the body, consisting of neurons and supporting cells called glia. Nervous tissue is essential for coordinating body functions and responding to stimuli.

Connective Tissue

A type of tissue that supports, binds together, and protects other tissues and organs in the body. Connective tissue includes various forms such as bone, adipose, blood, and cartilage.

Anatomical Planes: Frontal

Plane dividing front and back of body

Anatomical Planes: Sagittal

Plane dividing left and right side of body vertically

Anatomical Plane: Transverse

Horizontal at the midpoint of the body

Contralateral

On opposite sides of the body

Ipsilateral

On the same side of the body

Medial

Towards the center of the body

Lateral

Towards the edge of the body

Intermediate

Between a medial and lateral structure. Ex: The eye is intermediate to the nose and ear.

Proximal

Closer to the trunk or attachment of the body

Distal

Farther from the trunk or attachment to the body

Superior

Body parts closer to your head are

Inferior

Body parts closer to your feet are

Hypertonic solution

More solute outside of a cell than inside

Hypotonic

Less solute outside of a cell than inside

Does a channel require ATP?

No

Where is K+ most concentrated?

Inside the cell - Gradient will cause it to flow out

Where is Na+ most concentrated?

Outside of the cell - Gradient will cause it to flow IN

Where can we consider an action potential to have ended?

-70 mV

Where on the cell does an action potential start?
