covers the surface of body, lines body cavities + form glands
what is connective tissue role
supports, binds + protects other tissues / organs, also includes blood constituents
what is the role of muscle
contraction
what is the role of neural tissue
transmits electrical + chemical signals to coordinate body functions + responses
what is the central nervous system responsible for
integrating, processing, and coordinating sensory data + motor commands
what are the 2 components of the CNS
brain and spinal cord
what is the peripheral nervous system
all neural tissue outside the CNS which delivers sensory info to CNS and carries motor commands to peripheral tissue and organs
what are the constituents of the PNS system
- autonomic nervous system and somatic nervous system
- sympathetic nervous system and parasympathetic nervous system
