nervous system part 1
what is the central nervous systems Main parts?
Its made of the brain and spinal cord
what does the somatic nervous system allow us to do?
it allows us to consciously control out skeletal muscles
what tissue connects the skeletal muscle to the bone?
tendon
how many bones are in babies vs adults?
Most babies are born with about 300 bones while in the average adult human they have 206.
what are the 4 types of tissue?
connective tissue, epithelial tissue, muscle tissue, and nervous tissue
what is a motor division?
Carries impulses from CNS to organs, muscles and glands
what's a sympathetic nervous system?
its stimulates "flight or fight response"
what muscle is associated with raising your arm?
deltoids
what does the skeletal system protect?
It protects soft body organs such as the brain, heart, and lungs.
why does damaged cartilage heal slowly?
cartilage does not have a blood supply unlike other tissues
what keeps the Central nervous system informed of events going on inside and outside of the body?
the sensory division
what do visceral sensory fibers do?
transmit impulses from visceral organs such a as heart, liver and intestines
what are the major muscles associated with leg movement?

why is fat stored in bone marrow, what's its function?
Bone marrow produces blood cells and stores energy in the form of fat for overall good bone health.

what does the Appendicular skeleton consist of?
It consist of carpals, arm, and pectoral girdle feet, tarsals, leg, and pelvic girdle.
what do tissues help with?
it provide shape to the body and help body to conserve heat and store energy
what is an automatic nervous system?
Regulates involuntry events which is activity of smooth muscle cardiac muscle and glads
what's the diffrence between afferent neurons and efferent neurons?
efferent neurons carry motor info from the brain to the peripheral while afferent neurons carry sensory info from receptors in skin/ other organs to central nervous system
what is cardiac muscle?
Walls of the heart, attracted to the fibrous skeleton of the heart.
what does the Axial skeleton consist of?
It consist of bones of the skull, vertebrae, sternum, ribs and hyoid bone.
what's the diffrence between connective and muscle tissue?
Connective tissue binds the various parts of the body together, providing support and protection, while Muscle tissue allows the body to move
