01a: Intro Flashcards
Skin and superficial fascia are part of (external shell/internal cavities).
External shell
Axial skeleton/ribs are part of (external shell/internal cavities).
External shell
Thoracic cavity is part of (external shell/internal cavities).
Internal cavites
Pelvis is part of (external shell/internal cavities).
Internal cavities
Diaphragm part of (external shell/internal cavities).
External shell
Mediastinum is part of (external shell/internal cavities).
Internal (thoracic) cavity
Muscles of thoracic/abdominal walls are part of (external shell/internal cavities).
External shell
The (X) pattern of (Y) along (Z) axis of body in embryo dictates fundamental pattern of trunk.
X = repeating Y = somites Z= cranial-caudal
Muscles develop of (X) regions of (Y) in embryo.
X = myotome Y = somite
Bones, like vertebrae/ribs, develop of (X) regions of (Y) in embryo.
X = sclerotome Y = somite
Associated cartilage of ribs/vertebrae develops of (X) regions of (Y) in embryo.
X = sclerotome Y = somite
Skin develops of (X) regions of (Y) in embryo.
X = dermatome Y = somite
Nerves develop from which region of somite?
Don’t develop from somite, but grow into territories dictated by somatic pattern
Blood vessels develop from which region of somite?
Don’t develop from somite, but grow into territories dictated by somatic pattern
Mobile viscera are typically enclosed in (X). Less mobile viscera are located in/against (Y).
X = serous membrane Y = posterior body wall
External musculoskeletal shell will receive general (somatic/visceral) motor innervation from (X).
General somatic;
X = ventral primary rami of spinal nerves
Describe characteristics of general somatic (afferent/efferent) sensation.
Afferent;
Sharp and well-localized along that dermatome
Visceral innervated by (X) system, a division of (Y) system that typically operates (with/without) conscious control.
X = Autonomic NS
Y = Peripheral NS
Without
Describe characteristics of general visceral (afferent/efferent) sensation.
Afferent;
Vague, widely-distributed
The (X) system is divided into two distinct subdivisions, which are (Y) for fight/flight and (Z) for rest/digest.
X = autonomic Y = sympathetic Z = parasympathetic
Sympathetic nerves originate from which part(s) of SC?
Thoracolumbar
Parasympathetic nerves originate from which part(s) of SC?
Craniosacral
T/F: All sympathetic nerves pass from SC to sympathetic trunk, where they synapse.
False - all pass through, but may/may not synapse
(X) nerve(s) is/are parasympathetic and cranial in origin.
X = vagus
