Cells
What is Exocytosis and Endocytosis?
Exo: secretion; exiting the cell
Endo: things that are entering the cell
What are the type of tissues?
Connective, Muscle, Epithelial, and Nervous
Osteoblasts=
Osteoclasts=
= create osteocytes (builds)
= bone resorption (consumes)
Actin=
Myosin=
= thin filaments
= thick filaments
What does the nervous system include?
brain, spinal cord, and the nerves
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis (IPMAT)
Tendons=
Ligaments=
=muscle to bone
=bones to bone
Types of joints
saddle, pivot, hinge, ball and socket
What is the synapse in the neuromuscular junction?
gap between the neuron and motor end plate (synaptic cleft)
3 major parts of the brain
cerebrum, cerebellum, and the brain stem
Why is the Golgi Apparatus referred to as the "post office"?
It packages and delivers proteins produced by ribosomes, that are exported into the vesicles.
Epidermolysis Bullosa is a _____ tissue disorder?
Connective tissue disorder that cause the skin to blister easily
Diaphysis=
Epiphysis=
Articular Cartilage=
= ends of bone
= shaft of the bone
= cartilage covering the ends of bones
Neuromuscular Junction
Where a nerve and muscle come together
The lobes of the brain and their function
1. Frontal Lobe: help control thinking, planning, organizing, etc
2. Parietal Lobe: help interpret feelings, knowing sensory info, helps process taste, texture, and temperature
3. Occipital Lobe: process images from your eyes
4. Temporal Lobe: process information from your senses of smell, taste, and sound. Also play a role in memory storage
What is the relationship between cancer and mitosis?
Cancer is essentially a disease of mitosis causing uncontrolled cell division because of changes in DNA that cause for checkpoints to be ignored.
Muscle Type:
- Skeletal (location/ voluntary or unvoluntary)
- Smooth (location/ voluntary or unvoluntary)
- Cardiac (location/ voluntary or unvoluntary))
skeletal= skeletal muscles/ voluntary
smooth= in hollow organs (like the stomach)/ involuntary
cardiac= wall of the heart/ involuntary
The 4 Sutures
1. Coronal
2. Lambdoidal
3. Squamosal
4. Sagittal
In Myasthenia Gravis what is damaged?
The acetylcholine receptors are damaged
Anatomy of a neuron
2. dendrites: receives information
3. axons: conducts information away from the cell
What is Diffusion and Osmosis?
Diffusion: Molecules that tend to spread out, moving from a high to low concentration
Osmosis: The diffusion of water through a selectively permeable membrane
Cartilage is a type of ____ connective tissue? What are the types of cartilage?
dense
Hyaline Cartilage, Elastic Cartilage, and Fibrocartilage
What is the Foramen Magnum?
large openings through the bottom of the skull, where the spinal cord enters the skull
Sliding Filament Theory is the theory of what? and how does it work?
Theory on how muscles contract, troponin and Tropomyosin will block actin when muscle fibers are at rest and the ATP and Calcium will unblock the causing for ATP to bind with myosin and release actin.
Microglial Cells function=
Oligodendrocytes function=
Astrocytes function=
= immune function; digest debris, kills bacteria
= make myelin sheath that provides insulation around the axons
= connects blood vessels to neurons
