Chapter 1-orientation of body Flashcards
Anatomy
The study of the structure of the body
Anterior
Towards the front of the body
Distal
Furthest from the point of origin
Dorsal cavity
Located at the back of the body; containing cranial and spinal cavity
Frontal plane
Divides the body lengthwise into anterior and posterior portions
Homeostasis
The state of dynamic equilibrium of the internal environment of the body
Inferior
Beneath or lower
Lateral
away from the body’s midline
Medial
Towards the body’s midline
Negative feedback
When the effector opposes the stimulus and reverses the direction of change
Organ
Structures of two or more tissue types that work together to carry out a particular function
Organelle
Metabolic units (or tiny organs) within a cell that preform a specific function necessary to the life of the cell
Psychology
The study of how the body functions
Positive feedback
When the effector reinforces the stimulus and amplifies the direction of change
Posterior
Toward the back of the body
Proximal
Closest to the point of origin
Saggittal plane
Divides the body into right and left sides
Superficial
At or near a body’s surface
Superior
Situated above something else
Tissue
Specialized group of cells with similar structure and function
Transverse plane
Divides the body into upper and lower or superior and inferior portions
Ventral cavity
Located at the front of the body
The smallest living unit that makes up the body’s structure is
