Cell Structure
Define the Cell Membrane.
Also called the phospholipid bilayer, regulates what enters and leaves the cell. It is selectively permeable.
What are the four major type of tissues?
Epithelial, Connective, Muscle and Nervous.
What are the Functions of the Skeletal System?
The Skeletal System provides support and protection. It assists body movement. It's also responsible for blood cell formation and the storage of inorganic materials.
What are the two type of Myofilaments?
Actin and Myosin.
What are the three major parts of the brain?
The Cerebrum, Cerebellum, and the Brain Stem.
The Smooth ER is for lipid synthesis. While the the Rough ER has ribosomes on the surface and is involved in protein production and protein folding.
Where can you find Epithelial Tissue and what are its functions?
The epithelial tissue covers all body surfaces both inside and out.(Skin) Its functions include protection, secretion, absorption, excretion and senses.
What is hematopoiesis?
Blood Cell Formation.
What are the three type of Muscle Tissue?
Skeletal, Smooth and Cardiac.
List 5 Neuroglial Cells
1. Microglial Cells
2. Oligodendrocytes
3. Astrocytes
4. Ependymal Cells
5. Schwann Cells
The Cytoskeleton is made of...
The Cytoskeleton is made of microfilaments and microtubules for cell shape and support.
What are some type of Connective Tissue?
Loose Connective Tissue/Areolar Tissue, Adipose Tissue, Fibrous Connective Tissue, Cartilage, Bone Tissue, and Blood Tissue.
What is the difference between Osteoblasts and Osteoclasts?
Osteoblasts create osteocytes. Osteoclasts are responsible for bone resorption (Get rid of Osteocytes).
What is a muscle composed of? The bundles they are arranged in are called?
A muscle is composed of many fibers arranged in bundles called fascicles.
The Central Nervous System consists of..., while the Peripheral Nervous System consists of.....
The Central Nervous System consists of the brain and Spinal Card, while the Peripheral Nervous System consists of the nerves throughout the body.
What is Mitosis? What are the four stages of Mitosis?
Mitosis is the process where a cell divides into two identical daughter cells. The four stages of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.
What is nerve tissue made of?
Nerve Tissue consists of neurons, axons, dendrites and neuroglia.
What is the Long Bone structure?
Epiphyses are the ends of bone, Diaphysis is the shaft of the bone, Articular cartilage covers the ends of bone, Periosteum is the membrane covering the entire bone and the Medulla is within the Diaphysis and contains bone marrow.
What is the Muscle Structure Hierarchy?
1. Muscle
2. Fascicles
3. Muscle Fiber
4. Myofibrils : Actin and Myosin
What is the function of the Hypothalamus?
The Hypothalamus is responsible for managing heart rate, blood pressure and hunger.
What is the relationship between Cancer and Mitosis?
Cancer is a disease of mitosis. When the normal checkpoints regulating mitosis are ignored there is uncontrolled cell division.
What is another word for Bone Tissue?
Osseous Bone
List the different type of Diarthrotic Joints and an example.
Type of Diarthrotic Joints include Ball & Socket (shoulder & hip), Hinge (Elbow & Knee), Pivot (Lower Arm) , and Saddle (Thumb) .
Define the Sliding Filament Theory.
The theory of how a muscle contracts. The contraction of a muscle occurs as the thin filament slides past the thick filaments.
What are the two branches of the Peripheral Nervous System and what do they consist of?
The two branches of the Peripheral Nervous System are the Somatic Nervous System and Autonomic Nervous System.
The Somatic Nervous System consists of the skeletal muscles and is voluntary. The Autonomic Nervous System consists of Smooth Muscles and Glands. It is involuntary and divided into two branches: Parasympathetic and Sympathetic.
