Intro to A&P and Histology
The study of how the parts function and work together
What is Physiology?
The layer of skin that is composed of dense connective tissue and can be divided into 2 layers (papillary and reticular layers)
What is the dermis?
Part of the sarcomere, the "thick" myofilament
What is myosin?
The sensory division of the nervous system
What is the afferent division?
Provides cushioning and protection for the brain
What is cerebrospinal fluid or CSF?
The study of anatomy of a specific area of the body
What is regional anatomy?
Fingerprints are formed from ridges on the epidermis but originate here
What is the papillary layer of the dermis?
Bundles of muscle cells
What is a fascicle?
The 2 types of cells in the nervous system
What are neurons and neuroglia?
Part of the brain that controls the body's vital functions
What is the medulla oblongata?
State of equilibrium of the body with respect to its internal environment and its functions
What is homeostasis?
Functions of the skeletal system
What are support, movement, protection, storage of minerals/fats, hemopoesis?
This is formed when a myosin head attaches to the actin
What is a cross-bridge?
The resting potential charge inside the axon
What is -85 mV?
Control center for subconscious control of voluntary muscles (ie: balance, coordination)
What is the cerebellum?
This system detects a change in the body and produces the opposite effect
What is the negative feedback system?
A large, multi-nucleated cell that breaks down or kills bone
What is an osteoclast?
One motor neuron and all the muscle fibers it controls
What is a motor unit?
After the action potential is fired and the neuron returns to its resting potential
What is repolarization?
The lobe of the brain that controls all sensory information except smell, vision and hearing
What is the Parietal Lobe?
The 2 body systems that control homeostasis
What are the nervous and endocrine systems?
Gives bone it's flexibility and tensile strength
The collagen layer that differentiates one muscle from another
What is the epimysium?
The majority of synapse in the body are this
What is inhibitory?
The 3 layers or meninges of the brain
What are the dura mater, arachnoid mater and pia mater?
