Tissues, Anatomy Language, and Homeostasis (L1) Flashcards
Def. Anatomy (and Gross vs Microscopic)
The study of the structure and shape of the body
- Gross: studying large structures (heart, bones)
- Microscopic: study cells and tissues that can only be viewed under a microscope
Def. Physiology
The study of how the body and parts of the body function
Name the 6 levels of organization in order
Chemical, cellular, tissue, organ, organ system, organismal
Name the 4 types of tissue and their overall function
Connective - connect body parts
Epithelial - forms linings, coverings, and glands of the body
Muscle - contract and shorten to generate force to produce body movement
Nervous - receive and conduct electrochemical signals throughout the body
Connective Tissue (function, structure, components, examples)
Function: support, protect, and bind tissues
Structure: living cells surrounded by complex extracellular matrix
Components: ground substance and fibers
Ex: tendons, ligaments
Epithelial Tissue
- Covers internal and external body surfaces, forms boundaries
- Function: protection, absorption, secretion, filtration
- 2 surfaces: apical and basal
- Distinguished by # of cell layers and shape of cells
- Ex: skin, stomach lining
Muscle Tissue (function, types)
Function: movement of the body or organs
Types: skeletal, smooth, cardiac
Nervous Tissue (Function, Components)
Function: Control Body Functions
Components: neurons and neuroglia
- neuroglia functions: insulate, support, protect neurons
Describe anatomical position
Person standing upright and looking ahead with their hands to their side and palms facing forward (thumbs away from body)
Proximal vs. Distal
Proximal - towards the hip/shoulder of the body
Distal - away from the hip/shoulder of the body
Ex: thigh is proximal to the foot, the hand is distal to the wrist
Medial vs. Lateral
Medial - towards the midline
Lateral - away from the midline
(midline is a vertical line from head to toe)
Ex: Arms are lateral to the torso, the torso is medial to the arms
Superior vs Inferior
Superior - top
Inferior - bottom
Ex: Head is superior to the neck, the knee is inferior to the pelvis
Anterior (ventral) vs Posterior (dorsal)
Anterior - front of the body
Posterior - back of the body
Ex: the knee caps are located on the anterior side of the body, shoulder blades are posterior
