EXAM - Anatomy Flashcards
What are the main function of the skeletal system?
- Protection: skull & ribs
- Storage of minerals: calcium, salts, phosphorus
- Red blood cell production: carry oxygen & transport CO2 to lungs for exhaling
- Structure: framework that muscles attach to
- Movement: muscles contract or release, creating movement of bones
What is connective tissue?
What is fascia?
What is the difference between them?
- Connective tissue is the matrix that binds together the body’s organs and systems, while at the same time providing compartmentalization between them.
- Fascia, a specific type of connective tissue, is a
continuous sheath that exists from head to toe (like a bodysuit) that provides structural support for the skeleton and soft tissues (muscles, tendons, etc.).
What proteins make up connective tissue?
What are their qualities?
made up of elastin & collagen
- elastin: flexibility & pliability
- collagen: strong & stabilizing
What is tensegrity?
Continuous tension network, that creates stability without direct contact (bones connect via soft tissue).
If the tension network becomes weak = cannot support = it will be compensated somewhere else in the body.
Like a trampoline.
What role do the joints play in the body?
What are the most common ones?
Joints are connection points of two bones.
- plane joints
- ball & socket joint
- hinge joint
- ellipsoid joint
- saddle joint
- pivot joint
What are the varying degrees of mobility in joints called?
- functional range
- hypermobile
- hypomobile
How does yoga contribute to bone and joint health?
- yoga helps to maintain bone density: exercise causes small micro tears which makes for the regeneration of the bones
- low impact vs. high impact exercise
- minimal damage to cartilage
- increase in range of motion (ROM)
- less strain on joints due to stronger muscles
- helps to circulate synovial fluid: less friction in joints
What are the two main functions of fascia?
- Connection: attach, separate, support organs, fill space, communication, force transmission
- Protection: enclose, store fat, fight infections, insulate
What is the role of the nervous system in a human body?
Body’s control center and communications network
what are the 3 functions of the nervous system
- sensory: recognizing signals through your senses
- motor: controlling and activating the muscles, issues orders to muscles, glands and organs
- integration: transmits information, allow communication through the body
What are the two parts of the nervous system and their role?
Central Nervous System & Peripheral Nervous System
CNS: processes, interprets, stores information, issues orders to muscles, glands, organs
PNS: transmits information to and from the CNS
Explain sympathetic and parasympathetic nervous system
Sympathetic: Flight, fight or freeze, mobilizes body for action, energy output
Parasympathetic: Rest and digest, conserves energy, maintains quiet state
How can you impact the nervous system through yoga?
- Breath: different methods of breathing affect autonomic nervous system
- Asana: stimulate sympathetic (backbends, wheel, warriors) & parasympathetic nervous system (child’s pose, savasana)
- Meditation: stimulates parasympathetic nervous system
What is the role of the spine?
- supports & holds us upright
- houses spinal cord
- allows for flexibility and movement
What are the regions of the spine?
- cervical (C1-C7)
- thoracic (T1-T12)
- lumbar (L1-L5)
- sacrococcygeal (9 fused vertebrae in sacrum and coccyx)
How many vertebrae do you have? Explain how the vertebrael variations can impact a student’s yoga practice?
33 interlocking bones that form the spinal column
The shape of the aspects in each segment determines the ROM (functional range, hypermobile, hypomobile). Therefore you should consider vertebrael variations with students’ ability to access poses - uniform versus unique!
What movements from the spine?
- flexion (rounding) & extension (lengthening upwards & backwards)
- lateral flexion (side-body bending)
- rotation (twisting)
Most movement occurs in cerval & lumbar spine
