LAB 3 Flashcards
(23 cards)
Structure formed by a combination of 2 or more of the basic tissues
Organ
The organ is composed of a main tissue called ____ (which is unique for a specific organ and the functional part of the organ) and ____ (mostly connective tissue that
supports and forms the framework of an organ)
parenchyma, stroma
hollow organs with a canal (lumen) and a muscular wall
Tubular organs
solid organs with the typical parenchyma + stroma
Parenchymatous organs
structural support
and protection of vital organs
Skeletal System
The skeletal system is divided into 2 groups
- Axial System
- Appendicular System
follows the axis of the body; Skull, vertebrae (backbone), ribcage
Axial Skeleton
Arms (shoulders and collarbone, humerus, radius + ulna, carpals, metacarpals), legs (pelvis, femur, tibia + fibula, tarsals, metatarsal), and digits (phalanges)
Appendicular Skeleton
Functions are movement, control of body temperature
Organ system that is responsible for movement
Musuclar System
Organ system that controls long term activities like growth, metabolism, reproduction and development, and production of hormones
Endocrine system
General Functions
* Coordination and control of all body activities
* Rapid responses to emergency situations
* Perception & interpretation of sensory
information
* (in humans) Higher level thought processes;
planning, abstract thought, memory,
learning, speech
Nervous System
(the brain and the spinal cord)
Central Nervous System
(the nerves and
ganglia branching from the brain and spinal cord)
Peripheral Nervous System
Nerve cells of the PNS that are bringing information to
the brain are called ____
sensory neurons
Nerve cells that are taking information away from the brain out to muscles and glands are called ____
motor nerves
monitor the outside world and the internal environment to allow the body to respond quickly
and effectively to any potential dangers or threats
sensory system
Classification of sense organs
- Photoreceptors
- Chemoreceptors
- Mechanoreceptors
- Thermoreceptors
convert light energy into nerve impulses
photoreceptors
convert various chemicals in air or water into nerve impulses
Chemoreceptors
convert mechanical movements such as vibrations of air or water, pressure, and touch to nerve impulses
Mechanoreceptors
converts heat or cold into nerve impulses
Thermoreceptors
This organ system’s function are delivering food and oxygen to cells, maintaining salt/water balance and acid/base balance, and protects body from pathogens
Circulatory System
